Electrogas Welding For Low-Alloy Steel

LOW ALLOY STEELElectroslag wire

 

1.SELECTION RECOMMENDATION:


According to AWSA5.25, electroslag wire can be classified to solid wire and metal cored wire. Fluxes are classified by tensile strength and impact.

 

See below chart for classification and usage:

--

Classified to EWT1, EWT2, EWT3, EWTG.

 

 

 

2.Welding Operation


(1)Storage


①The packing of drum pack should avoid any depression by crashing, because it will cause the wire crossed.

②The drum pack, normally used with paper packing material, should be store in the environment without high temperature and humidity. 

 

(2)Note


①Before using, check if the wire is crossed, and the direction of guide board is correct.

②When automatic wire feeding machine works with swing function, check if the swing is smooth, to avoid incomplete melting.
