Steel pipe welding

When welding steel pipe is firstly liquidation clean welded joints of oil, paint, water, and rust, and then based on wall thickness open groove, thick open and thin open smaller (angle grinder), then the gap is the right product common, which is the welding rod or wire diameter 1 - 1.5 times, if you groove, be careful not to open a speech appropriately to stay small. Tack welding at least three points, four points incomparable good work.

After midnight should be half-and-half welded steel pipe welding, the starting point for the best beyond the lowest point is one centimeter or so, so good joints from the opposite.

If the wall thickness of the pipe should be stratified at least two layers, the first layer of the whole ring of solder until they have finished welding the second layer.

Welding also known as welding, Rong is a way of heating, high-temperature or high-pressure bonding metal or other thermoplastic materials, such as plastic manufacturing processes and technologies.

Weld through the following three ways to achieve joint objectives:

Heating of bonding the workpiece to partial melting into pools, joint after solidification of molten pool and, if necessary, may join the molten filler accessory.

Heating of low melting point solder alone, without having to melt the workpiece itself, and solder the capillary connection parts.

Equal to or lower than the melting point of workpiece temperatures combined with high pressure and vibration of laminated plastic or mutual penetration between the two workpieces, such as joint
