Description

Product Detail

Application

Applying for welding pearlitic heat-resistant steel (eg:12CrMoV) which working temperature lower 540? and seam welding of boiler pipe ( backing weld using manual hydrogen arc welding).

Characteristic

CO2 shielded flux cored wire for Cr-Mo heat resistant steel is based on titania type with slag system. It has the advantages of arc stability, gentle performance. Suitable for all position welding. The preheating and interpass temperatures are 250-300? when weld.

Flux Cored Wire Basics

There are two types of flux cored wires: gas shielded and self shielded. Gas shielded flux cored wires require external shielding gas and the slag is easy to remove. The operator may want to consider using gas shielded flux cored wires when welding on thicker metals or in out-of-position applications. Gas shielded flux cored wires have a flux coating that solidifies more quickly than the molten weld material. As a result, it creates a "shelf" to hold the molten pool when welding overhead or vertically up. Self shielding flux cored wire does not require external shielding gas; the weld pool is protected by gas generated when flux from the wire is burned. As a result, self shielding flux cored wire is more portable because it does not require an external gas tank.
