Teach you several welding demagnetization methods, very practical source: Welding Home Release time: November 25, 2015 In the production of oilfield construction units, it is common to encounter welding of magnetized pipelines due to the large magnetic bias blowing during the welding of magnetized pipes. Poor weldability. The article mainly introduces the use of DC demagnetization electrode arc welding, AC demagnetization electrode arc welding, and electrode arc welding with electromagnetic or permanent magnet demagnetization for magnetizing tubes.

The art of tungsten electrode polishing: creating perfect welding!

The art of tungsten electrode polishing: creating perfect welding!

2024-12-06

Tungsten electrodes are divided into pure tungsten, thorium tungsten, cerium tungsten, lanthanum tungsten, etc. Currently, the most common ones on the market are thorium tungsten and cerium tungsten. Tungsten electrode generally refers to cerium tungsten electrode. Cerium tungsten electrode is a tungsten electrode product made by adding rare earth cerium oxide to tungsten base through powder metallurgy and rolling grinding and polishing processes.

Tungsten electrode is made of materials with high melting point, corrosion resistance, high density, good thermal and electrical conductivity. Tungsten electrodes are widely used for welding due to their properties. The final colors are all different, and the differences can be distinguished.

Technical Parameters in Argon-arc Welding

Technical Parameters in Argon-arc Welding

2024-11-15

Argon-arc welding is one of the most popular welding type. The welding performance is related to the flowing parameters:

  1. Type and valueof welding current
  2. Tungsten electrode diameter and end shape
  3. Gas flow rate and nozzle diameter
  4. Welding speed
  5. Distance better nozzle and workpiece

After setting these above well, you can get good argon-arc welding experiences

Fish-Scale Weld were Originally Welded Out Like This

Fish-Scale Weld were Originally Welded Out Like This

2024-10-31

TIG welding is a welding method in which pipes are directly welded to each other, forming a fish scale shape, also known as fish scale welding.

Welding method

The main process is to select the welding point, power on, use the welding rod head to strike an arc, melt the flux in the welding rod, and then swing the welding clamp slightly left and right to evenly melt the welding core at the welding position It should be called fish scale welding because if the welding effect is good, it will look like fish scales.

Do you know how such beautiful fish scale patterns are welded together?

The editor has compiled some videos and materials, let's take a look together.
