VILCHIS 8018-C1 FOR (C.A.C.C.) ARC

SPECIAL WELDING ROD WITH A LOW HYDROGEN CONTENT AND POWDER IRON COVERING. ITS FILLER METAL HAS HIGH MECHANICAL RESISTANCE AND IT IS A LOW NICKEL ALLOY.

   

CLASSIFICATION A.W.S: E8018C1

IDENTIFICATION: GREY COATING

APPLICATIONS: It is recommended for the production and maintenance of pressure vessels, cast parts, and low temperature pipes (as low as 60C ) and to weld low alloy steel with a nickel content between  2 and 2.7%.
Vilchis 8018C1 welding rods can be used with excellent results with the following kinds of steel  (ASTM specifications):
A 203 - 74a ooooooGr. A y B
A 352 - 74a ooooooGr. 1C2
A 334-74 ooooooooGr. 7
A 350 - 74 oooooooGr. LF1 and LF2
A148-73 oooooooo Gr.80,40 and 50

CHARACTERISTICS AND PROCEDURE: This electrode can be used in all positions except when welding vertically downwards. Its filler metal looks nice and has neither cavities nor splatter.

Clean the joint area to remove dirt, scales, grease and rust. Keep the arc short with the welding rod slightly tilted in the direction of the weld. Swinging while welding should not triple the core diameter. When using DC, connect the electrode holder to the positive pole (reverse polarity). Remove the slag between one pass and the next.
Precaution: Electrodes with low hydrogen content coverings are higroscopic (they tend to absorb and retain the water from the surrounding air) so they should be kept in a dry, hot place.
