There are indentations on the welding surface of the energy storage welder

What causes indentations on a weld surface?

The indentations on parent metal or weld surfaces, known as mechanical damages, are brought on by defects that arise during the welding process. They may arise from incorrect selection of welding equipment or techniques. Using more force when chipping; ineffective use of a grinder

What is an indentation in welding?

Relatively high electrode forces are used to contain the melted material and to minimise heating between the electrode and the sheet surface. An indentation is normally produced on each sheet surface during welding, up to 10 or 20% of the sheet thickness, when the softened material is squeezed by the electrodes.

Where do superficial welding defects appear?

Superficial or visual defects manifest on the surface of the metal weldment. Welding faults and defects can be categorized according to their location in the metal. They may be external or internal.

What causes a weld discontinuity?

Keep the weld axis in horizontal by positioning. weld discontinuity in which fusion did not occur between weld metal and joint fusion face or between adjoining weld beads. Main Causes: Too narrow welding groove Preventive Measures: Use appropriate welding parameters and groove angles. Use an appropriate groove configuration.

Can welds fail?

Yes, welds can fail. Weld defects are common in sheet metal welding and can weaken the joint or cause complete product failure. These defects generally occur due to wrong welding methods or incorrect welding patterns.

What are welding defects?

Welding defects are simply the defects of welding that can either be external or internal. Well, there are many types of welding defects, and so are the causes of welding defects. But what are these? Don’t worry. We will tell you all the common welding defects and their causes and will try to give the remedies to cater to these defects as well.
