DESCRIPTION AND APPLICATION
- TIG 70S6 is designed for welding of mild steel and 490N/mm2 grade steel.
- Commonly used is butt or fillet welding of high pressure piping for shipbuilding, petro chemistry and nuclear power plant, etc.
- As an all-position welding rod for TIG welding, it is especially suitable for the root pass of pipe welding.
- Use DC(-) polarity.
- 100% Argon shielding gas with 99.997% high purity is recommended and the flow rate must be properly controlled.
- The flow rate is recommended 7-12l/min when arc current is 100-200Amp and it goes up to 12-15l/min when arc current rises to 200-300Amp.
- Select right gas cup size and employ proper stick out of tungsten electrode.
- To obtain a very clean weld pool, keep the weld plate free from dirt, rust, paint and any other atmospheric contamination.
- Trailer Shield is required to ensure the weld pool completely shielded until solidification is complete and no porosity problem.
