Pyramid Industry Limited is a professional welding machine manufacturer in China, who is willing to share knowledge about welders. Today we would like to introduce the top 3 seam welder working methods. According to the wheel electrode rotation (weldment movement) and the past welding current of the machine - electricity cooperated way, the working method can be divided into the following type:

1. Continuous seam welding

The method is that the roller electrode continuously rotate, welding pieces shift at a constant speed, welding current goes through constantly and form a solder joint every half cycle. The welding speed of this method can be up to 10 to 20m / min. But the actual application of welding by this method is limited due to the poor quality of the welding surface.

2. Intermittent seam welding

Weldment moves at a constant speed, the welding current goes through intermittently. Each "on - off" will form a solder joint. According to the thickness of weldment, the speed can be up to 0.5 to 4.3m / min. It has wide range of applications: black metal gas, water, oil sealed weld productions.

3. Step seam welding

Weldment intermittently moves, and the welding current passes through at the time the weldment stop moving. Each "stop-move" forms a solder joint, and can be exerted forging force. The formation of the joint is very similar to solder joint’s. The welding speed is low, generally only 0.2 to 0.6m / min. And it only applies for manufacturing the aluminum alloy and magnesium alloy high-sealed weld.
