VILCHIS 9018-B3 FOR (C.A.C.C.) ARC

SPECIAL WELDING ROD WITH A LOW HYDROGEN CONTENT AND POWDER IRON COVERING. ITS FILLER METAL IS A LOW CHROMIUM-MOLYBDENUM ALLOY WITH HIGH MECHANICAL RESISTANCE.

CLASSIFICATION A.W.S: E 9018-B3

IDENTIFICATION: GREY COATING

APPLICATIONS: It is recommended to weld equipment and devices in which the working temperatures reach up to 625C as boilers, transformers, converters, oil refinery high temperature pipes (cracking tubes), heat exchangers, etc.

Vilchis E-9018B3 electrodes are recommended for the following kinds of steel ( ASTM   specifications):
A 199 - 64 Gr. T3 and T4 ooooooooooooooooooooooo A 356 - 65 Gr. 4,8 and 10
A 200 - 64 Gr. T22. ooooooooooooooooooooooooooA 234 - 65 Gr. WP
A 213- 64 Gr T22. oooooooooooooooooooooooooooA 369 - 65 Gr FP21
A 217 -65Gr.WC9 oooooooooooooooooooooooooooA 356 - 74 Gr. 5
A 335 - Gr. P22 and P21 A 369 - 65 Gr. oooooooooooA 336 - Gr. F22 A 542-C1 1/2
A 389 - 63
A 199 - 64 Gr. T3 and T4 oooooooooooooooooooooooA356 - 65 Gr. 4.8 Y 10
CHARACTERISTICS AND PROCEDURE: This electrode filler metal has a very nice appearance and the resulting weld seams are flat, smooth, without cavities or splatter. The slag can be easily removed. It can be used in all positions.
Clean the joint area to remove dirt, scales, grease and rust. Keep the arc short with the electrode slightly tilted in the same direction as 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 a low hydrogen content covering are hygroscopic (they tend to absorb and retain water from the surrounding air) so they should be kept in a dry, hot place.
