This document provides a prequalified welding procedure specification (WPS) for shielded metal arc welding (SMAW) of lap joints with fillet welds in various positions.

This WPS shall be used in conjunction with the General Welding Standards (GWS) and Welding Fabrication Procedure (WFP) sections and criteria for joint details, repairs, NDE, inspection etc. Weld Joint Type: Class:

Sep 29, 2010 · I am unsure how to write a prequalified WPS using D1.1. I want my students to do an open root on 3/8 plate with 6010 root and 7018 fill and cover. Is there a prequalified proceedure that covers this, or do I have to buy a WPS?

Sep 9, 2014 · wps 7018+70s2 This document is a Welding Procedure Specification (WPS) outlining the requirements for welding pipe joints for various piping classes using gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) processes.

I'm aware that putting in a hot pass with 7018 can be more prone to slag inclusions and incomplete fusion depending on how the root and subsequent grinding of the root went. When a WPS has a root pass of 6010, that has a max deposition of 1/2"thick, and the fill/cap requires 7018 would/could you justify a hot pass with 6010 as long as it does ...

Jul 16, 2009 · ASTM A36 can be welded with E6010 as long as the preheat is in accordance with Table 3.2 for the thickness being welded. Likewise, E7018 can be used as well, but the preheat requirements are somewhat lower for a given thickness when compared to the E6010.

Notes, Technique or Code Guidance: -Number of passes varies based on joint configuration, position, electrode size, travel speed, and weld technique. -First pass should be large enough to minimize the possibility of cracking.
