How do you find the travel angle of a weld?
The angle is measured in the plane containing the weld axis and the electrode axis. The travel angle shown is about 20°. When the top of the electrode leads the welding end of the electrode, and the welding arc is pointing back toward the weld bead, the travel angle is called a drag angle or a drag travel angle.
What angle should a MIG welding gun be pointing?
Horizontal welding is a little harder. The MIG gun should be pointing upward between 35 to 45 degrees and tilting about 15 to 35 degrees toward the direction of the weld. You need to watch out for overlap and the weld rolling over.
What is the electrode travel angle for a fillet weld?
The electrode travel angle for a fillet weld is measured in a plane defined by the weld axis and the electrode axis. In this drawing, the electrode is at a forty-five degree angle from the base metal. The travel angle is the angle between the electrode axis and an imaginary line in the plane that is perpendicular to the weld axis.
What is drag travel angle in welding?
When the top of the electrode leads the welding end of the electrode, and the welding arc is pointing back toward the weld bead, the travel angle is called a drag angle or a drag travel angle. This is also known as backhand welding.
What is the travel angle used?
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. The proper travel angle for a groove weld is typically about twenty degrees, but may range from zero degrees to about forty degrees, depending on the application.
What is a good travel angle to use while welding?
approximately 5 to 15 degreesAngle of travel: Stick welding in the flat, horizontal and overhead positions uses a drag or backhand welding technique. Hold the electrode perpendicular to the joint, and then tilt the top in the direction of travel approximately 5 to 15 degrees.
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 correct work angle?
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. With a fillet (tee) weld, hold the rod or wire (regardless of weld process) at a 45° angle between the two pieces of metal.
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.
How travel angle affects the quality of weld bead?
A travel angle of 0° to 10° (i.e., the electrode perpendicular or mostly perpendicular to the plate) will result in more weld penetration. As the travel angle becomes more severe, the level of weld penetration will decrease.
What is travel speed in welding?
Travel speed refers to how fast the welding arc is moving relative to the workpiece. The heat input equation clearly shows that travel speed, like current, plays a direct role in the amount of heat into the part. Faster speeds produce less heat into the part and reduced weld metal deposit.
What is 1G 2G 3G 4G 5G 6G welding?
The positions of groove welds are divided into 1G, 2G, 3G, 4G, 5G and 6G, respectively indicating flat welding, horizontal welding, vertical welding, overhead welding, horizontal fixed welding of pipeline and 45 °inclined fixed welding of pipeline.
What is the correct travel speed in welding?
The suggested travel speed for SMAW is 3 to 6 inches per minute (ipm) / 75 to 150 mm/min. SMAW of Ni-base alloys is not well suited for out-of-position welding and generally only feasible with 0.093 in (2.4 mm) and 0.125 in (3.2 mm) diameter electrodes.
What is 1G in welding?
1G Position In the 1G welding position, the pipe is in the horizontal position and can be rotated along the horizontal (X) axis. The welder's position remains stationary. Welding is performed on the top of the pipe. This is the most basic welding position that can be performed.
What travel angle is used for vertical welding?
The centerline of the electrode should be held at a 45° work angle. 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.
1. Characteristics of welding direction and angle
For gas metal arc welding, when the operator holds the welding gun with his right hand, it is welded from right to left.
2. Application of welding direction and angle
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.
3. Conclusion
3.1 The left welding method has the characteristics of shallow penetration and wide weld bead, which is suitable for thin plate welding;
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 weaving welding?
Weaving Welding Technique Pattern. Weaves are used for wider welds and range from a tight side to side motion that can be a stringer bead to welds that are wide and big for a single pass. Weaves are good for big joints that have no distortion issues. Just as a note in most shipyards weaving is not allowed.
How far should a MIG gun be pointing?
The MIG gun should be pointing upward between 35 to 45 degrees and tilting about 15 to 35 degrees toward the direction of the weld. You need to watch out for overlap and the weld rolling over. Always keep it to a tight stringer beads on any joint. Whipping and circles work best here.
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 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.
