VILCHIS MICRO WIRE

MICRO WIRE TYPE SOLID ELECTRODE WITH THIN COPPER COATING. IT IS USED WITH LOW CARBON STEEL IN ALL WELDING POSITIONS. 

CLASSIFICATION A.W.S: ER-70S-6

APPLICATIONS: Vilchis microwire is used in the railway, marine, oil, petrochemical and automotive industries. It is also used in the manufacture of metal furniture, in the construction of bridges, towers, tanks, boilers, pipes, frames, piers, etc.

CHARACTERISTICS AND PROCEDURE:Vilchis Microwire is used in the semi automated (GMAW) process or in  M.I.G.process where CO2, Argon-CO2  and Argon-O2 mixtures are used as shielding gas. This welding rod can be efficiently used with short arc or "Spray" type arc to produce a dense, mild, pore free weld of excellent appearance and mechanical properties.

PROCEDURE: Use reverse polarity DC. Filler metal transfer is achieved through repeated short circuits--"Spray" type--to produce an excellent looking weld which is free from defects and highly reliable for X-ray testing.
