1. PoreDuring the welding process, bubbles in the molten pool fail to escape during the solidification process, leaving a formed cavity.Cause: Harmful gas pollution such as hydrogen and nitrogen.Pr...

Due to the fact that the heat generated by the resistance is proportional to the square of the passing current, welding current is the most important factor in generating heat. The importance of we...

1. Automotive aluminum alloy wheels have argon arc welding, electric welding, and gas welding. The welding effect of these welding methods is that argon arc welding is better than electric welding,...

In the welding process of fully automatic flash butt welding machines, defects such as welds, solder joints, and arc pits often occur due to external or internal factors. This is the reason for the...

The medium frequency spot welding machine is energized based on the pressure of the electrode on the welded part, and generates Joule heat (instantaneous) based on the contact resistance between the e

1. The secondary voltage of intermediate frequency DC spot welding machines is generally relatively low, and there is no risk of electric shock. But the primary voltage is high voltage, and the primar

My mother's bravery lies in waiting for us to come to the world, knowing that we cannot inspect or return the goods with great anticipation. Time is not the thief who stole my mother's youth, you are!

520 I ❤ The busy life of U cannot stop. We strive hard for our dreams and family. Occasionally, we also need to stop and find an opportunity to express our love that is not easily expressed in daily

Resistance spot welding machine is a kind of equipment that uses Joule heat generated by electrified electrode to weld workpiece instantaneously, so as to achieve rapid welding of workpiece. Especiall

April Fools'Day This is a naughty day, mischief seems to be its main color. On this day, some people will confess without hesitation, while others will recklessly "play tricks" on their friends. In sh
