What is the angle of Fillet welding?
With a fillet (tee) weld, hold the rod or wire (regardless of weld process) at a 45° angle between the two pieces of metal. Speed: Watch the welding puddles and ridge (where the molten metal solidifies). When wire welding (MIG or flux-core), the ridge should be approximately ⅜ inch behind the wire electrode, Hoes says.
What is the travel angle used for most welding?
20 degree travel angle.
What is the travel angle for SMAW?
approximately 5 degrees to 15 degreesAngle Of Travel When welding on a flat surface, the SMAW techniques that you need to use are the backhand or drag (for flat and horizontal positions). Hold the welding stick perpendicular to the part where the materials are to be welded and then tilt at approximately 5 degrees to 15 degrees.
What is the travel angle of electrode?
An electrode's travel angle is measured in a plane defined by the weld axis and the electrode axis. The travel angle is the angle measured between the axis of the electrode and the axis of an imaginary line perpendicular to the weld axis.
What is the angle at which you travel down the joint called?
Travel angle. Angle at which the electrode travels down the joint. Travel speed. Speed at which the electrode moves down the joint. Arc.
What is the difference between work angle and travel angle?
Work angle is “the relationship between the axis of the electrode to the welders work piece”. Travel angle refers to employing either a push angle (pointing in the direction of travel) or a drag angle, when the electrode is pointed opposite of travel.
What is 1G 2G 3G 4G 5G 6G welding?

What travel angle is used for vertical welding?
As with welding on other joints in other positions, a travel angle of 5°–15° is a good angle to use. A C-shaped weld pool indicates good fusion is occurring. Short-circuiting transfer and pulsed spray transfer are best suited for vertical welding. Spray arc can be used with a weaving motion in some applications.
What is 5G position in welding?
5G welding position is a situation where the pipe is in the horizontal or X-axis position, but the pipe is stationary or cannot be rotated. The welder performs the welding while moving it around the pipe. This situation is almost the same as the 1G situation; only the pipe cannot be rotated.
What is the correct arc length for SMAW?
Correct arc length is re- lated to electrode diameter. Examine the weld bead to determine if the arc length is correct. Arc length for 1/16 and 3/32 in. diameter electrodes should be about 1/16 in.
What are the 5 SMAW operation set up?
SMAW Operation Set-upClean the workpiece.Clamp the work close to the weld.Insert the electrode into the insulated holder holder. Set amperage at levels recommended by the electrode manufacturer.Determine the best arc length. ... Have a chipping hammer available to remove any slag and before doing a 2nd pass with the weld.
Which welding process is used for welding in 360 degree?
Endless rotation arc welding torches allow 360-degree rotation, which comes with many benefits. Endless or continuous rotation arc welding torches are a significant step forward in robotic welding operation, especially when performing radial welds.
What are the principles for SMAW operation?
Principles of Operation The SMAW process uses an electric circuit that supports a welding arc to convert electric line power or fuel into heat. The heat from the welding arc is intense and extremely concentrated. It immediately melts a portion of the workpiece and the end of the electrode.
What angle to push wire?
Otherwise, you push the wire with metal inert gas (MIG) welding. Work angle: With wire welding, hold the gun at a 10° to 15° angle into the direction you are pushing the weld. With stick welding, maintain a 20° to 30° lead angle in the dragging direction.
How far should arcs be from the welding pool?
Arc spacing: Adjust travel speed so that the welding arc stays within the leading one third of the weld pool. For wire (flux-core or MIG) welding, keep a work distance of ⅜ to ½ inch. With stick welding, look to keep that distance ⅛ inch between the rod tip and work piece. “The arc length should not exceed the diameter of the core of the electrode,” Leisner says. In the image below from left to right, too short arc spacing, normal arc spacing, and too long arc spacing.
How far should the ridge be behind the wire?
When wire welding (MIG or flux-core), the ridge should be approximately ⅜ inch behind the wire electrode, Hoes says. A too-slow travel speed produces a wide, convex bead with shallow penetration that also deposits too much metal.
Is welding hard and fast?
However, Karl Hoes of Lincoln Electric and John Leisner of Miller Electric caution that there are some hard-and-fast rules to produce a lasting welding repair. Push or pull: Here the rule is simple.
What is the angle of welding called?
When welding in the right direction, it is called caster angle, and when welding in the left direction, it is called rake angle.
What is the angle between the nozzle and the welding direction called?
The nozzle of the welding gun has an obtuse angle (> 90°) with the welding direction, which is called left welding method; Welding from left to right, with an acute angle (<90°) between the welding gun nozzle and the welding direction, is called right welding method.
What is the impact of welding direction?
Since the welding direction and angle have an important impact on weld formation, spatter size, gas protection effect, etc., in the actual welding production, according to different technical requirements and actual conditions, left welding and right welding also have different application occasions.
What is the angle between the axis of the welding gun and the surface of the weldment?
The angle between the axis of the welding gun and the surface of the weldment is the working angle;
What happens when the travel angle is large?
When the travel angle is large, it has the characteristics of small penetration and poor weld pool protection effect.
Which welding method has the characteristics of shallow penetration and wide weld bead, which is suitable for thin plate?
3.1 The left welding method has the characteristics of shallow penetration and wide weld bead, which is suitable for thin plate welding;
Which part of the welding process acts directly on the weldment?
Most of the arc acts directly on the weldment during right welding, while most of the arc acts on the liquid molten pool during left welding.
How to weld a MIG gun vertically?
The MIG gun needs to be tilted up between 35 to 45 degrees. There is a trick to welding vertical down. You need to stay ahead of the puddle and keep the electrode moving from side to side. Otherwise the weld will not penetrate properly. Patterns don't really count as long as you stay ahead of the puddle.
How to MIG weld?
There are two ways to MIG weld. The first and the most common is to push the MIG gun toward the direction of the weld, this is called forehand method. Forehand welding produces shallow penetration with a flat wide smooth surface. The second is backhand method where you drag the MIG gun like a Stick welder.
What is the best way to weld a MIG gun?
Flat Position MIG Welding Techniques. Flat welding is the easiest. Typically the MIG gun will be pushed, the angle of the MIG gun can be pointing straight down to leaning toward the direction of the weld up to 35 degrees. Use a high voltage setting that runs fast and hot.
What is the smallest factor in MIG welding?
Nothing works all of the time and it comes down to what works right for you. Weld techniques are the smallest factor in MIG welding!
What degree should a MIG gun be pointed?
Vertical up is the most difficult of the MIG welding positions. The MIG gun handle should be pointed up between 35 to 45 degrees. When welding vertical up you need to build a shelf of weld to work upward on. The vertical up weld in MIG is typically very convex.
What is steady motion welding?
A steady motion is the most basic technique and requires the MIG welder be set exactly as needed. It is what most robots use to weld and it can produce a perfect weld in any position. It comes down to machine settings, electrode angle and travel speed. The basics of a steady motion are the hotter the setting in most cases the better the weld. There is not much to this technique except get everything set right. I do want to mention this is the techniques used for most out of position aluminum MIG welding. Besides that it is all self explanatory.
What is the most important part of MIG welding?
When it comes to MIG welding a properly set up machine is the most important part. MIG welding is easy but machine set-up it critical and requires a strong knowledge of the proper settings. Other processes like Stick and TIG you can get away with a machine that is not set exactly right.
