TASETO GFW310E is used for welding AISI310 or SUS310S and welding dissimilar metals such as stainless steel and carbon steel combinations. Weld metal has excellent corrosion resistibility and heat resistance, because of the higher content of Cr and Ni than Type 308 weld metal.

Notes on Usage

Please refer to “Guideline for Welding Stainless Steel with GFW Wires”.
* Because of the fully austenitic structure of weld metal, the weld metal susceptibility to hot cracking is high. So, the welding current must be kept within 150～200A. In the case of highly restrained conditions, it must be kept within 150～170A. Keep the interpass temperature at 120℃ or below. To minimize crater cracks, fill craters with filler metal and remove crater cracks with a grinder.

The labor-saving and rationalization are urgent issues to the welding industry. Spatter generated during welding work not only adversely affects the finish appearance of a welded product but also the time required for removing the spatter cannot be neglected.
TASETO SPANONs are anti-spatter agents, which are to solve these problems. TASETO SPANON will help rationalize your welding work and, at the same time, improve the quality of your welded products.

Feather

1. Excellent effect on preventing spatters from depositing on base metal during welding.
2. not influence welding.

Applications

Ferromagnetic metals (mild steels, high

● Features

1. Excellent in detecting surface flaws on ferromagnetic steels (unusable for non-magnetic materials).
2. Can also detect flaws that are not open to the surface.
3. Low testing cost
4. LED Blacklight is cordless

● Principle

Applying a high current to a magnetized object, or exciting an object placed in a strong magnetic field causes the magnetic field to bend by discontinuities such as cracks or pinholes, which exist on the object surface or relatively shallow subsurface, to leak out at the defective surface as if magnetic poles were produced there. If you apply TASETO JIKI CHECK to the leakage surface, its magnetic particles are absorbed over a wide range by the defective surface, thus making minute flaws visible to the naked eye. The magnetic particle testing method employs the principle.
