The robot welding adopts argon-rich mixed gas shielded welding, and the welding defects in the welding process generally include welding deviation, undercut, porosity, etc., which are analyzed as follows:
(1) The welding deviation may be due to the incorrect position of the welding or the problem of finding the welding gun. In this case, it is necessary to consider whether the TCP (welding torch center point position) is accurate and adjust it. If this situation occurs frequently, it is necessary to check the zero position of each axis of the robot and re-calibrate it to correct.
(2) The undercut may be due to improper selection of welding parameters, the angle of the welding gun or the position of the welding gun, and the size of the power can be adjusted appropriately to change the welding parameters, adjust the attitude of the welding gun and the relative position of the welding gun and the workpiece.
(3) The pores may be poor gas protection, the primer of the workpiece is too thick or the shielding gas is not dry enough, and it can be dealt with by adjusting accordingly.
(4) Too much spatter may be due to improper selection of welding parameters, gas composition or too long extension of the welding wire, the size of the power can be adjusted appropriately to change the welding parameters, the gas ratio meter can be adjusted to adjust the gas mixture ratio, and the relative position of the welding gun and the workpiece can be adjusted.
(5) An arc pit is formed at the end of the weld after cooling, and the buried arc pit function is added to the working step during programming, which can be filled.

The "peripheral" parameters of Korea's Hyundai Heavy Industries robot - arc welding robot
Welding velocity refers to the linear velocity of the arc moving along the welded joint. All other things being equal, a medium welding speed is the maximum penetration depth. As the welding speed decreases, the amount of deposited metal per unit length of weld increases. At very slow welding speeds, the welding arc impinges on the weld pool, not the base metal. ...
