The purpose of the Welding Procedure Specifications (WPS) and Procedure Qualification Record (PQR) is to . determine that the weldment proposed for the con-struction is capable of providing the required proper-ties for its intended application. NCPWB form QW-484 and pre-completed Welder .
Body Repair Manual Welding & Sectioning Guideline MAG WELDING WIRE SELECTION GUIDELINES Welding wire used during high-strength-steel repair must have a tensile strength equal to or greater than the lowest tensile strength of the parts being welded. Typical ER70S-6 wire has a minimum tensile strength of 70 ksi (483 MPa). This wire can be used when welding up to 440 MPa steel parts.
WELDING can cause fire or explosion. Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers. Do not weld where flying sparks can strike flammable material. Protect yourself and others from flying sparks and hot metal. Be alert that welding sparks and hot materials from

Guidelines for Welding - PCIFig. 1. Welding of ga lvanized steel. Cas Metal Arc W elding Gas metal arc (GMA) welding, also known as C02 or Metal-Inert Gas (MIG) welding, is a versatile semi automatic welding process that is con venient and easy to use. Fig. 2 shows an illustration of C02 welding. GMA welding is particularly suited to the welding of thinner materials.

How to write a Welding Procedure Specification (WPS A welding procedure specification (WPS) is a written document providing direction to the welder (or welding operator). It contains all the necessary parameters viz. joints, base metals, filler metals, positions, preheat, PWHT, gas etc. (including ranges, if any) under which the welding
Inspection and Testing for Welding Procedure QualificationWelding Procedures are the guidelines used to perform a weld. They are designed to provide a record of the welding variables used and the inspection results obtained during the procedure qualification test. They can also provide the instructions for the welder to use in
New guidelines for developing welding procedures are provided in the chapter on standards, codes and specifications. Estimating is expanded and provides both a short and long method of estimating welding costs with examples. Welder training is updated and covers the International Training Fund (ITI) welding program and welder qualification.
WELDING PROCEDURE SPECIFICATION Shielded Metal 1.2 The attached Welding Procedure Data Sheets (WPDS) are an essential part of this WPS. 2.0 WELDING PROCEDURE 2.1 The Welding shall be done manually using Shielded Metal Arc Welding, SMAW process. 2.2 Joints shall be made following the procedural stipulations indicated in CSA Standard W59-13 and may consist of single and multi passes in accordance with the approved Welding
Welding Safety Tips and Guidelines - Quick Tips #109 Welding Safety Precautions. The Occupational Safety and Health Administration (OSHA) provides basic fire prevention and protection precautions to follow in the welding, cutting and brazing standard found in 29 Code of Federal Regulations (CFR) 1910.252(a).
Additionally, in order to qualify a procedure for in-service welding for all positions, API 1104 indicates that a test rig in which the longitudinal axis of the pipe is held at 45° to horizontal should be constructed. This test rig qualifies welding in all positions and when filled with flowing water should generate more severe thermal cooling conditions than those typically encountered during in-service welding.
Welding and Joining Guidelinesspecific welding procedures. The general welding guidelines and any alloy-specific welding considerations should be used to develop a specific welding procedure. Weld Joint Design Selection of a correct weld joint design is critical to the successful fabrication of HASTELLOY® and HAYNES® alloys. Poor joint design can negate even the most optimum

Welding-procedures and work instructions:from intentions Welding-procedures convey the required information to the workers performing welding operations.. They also assist in controlling workmanship and consistency.. Welding Procedure Specifications (WPS) are detailed welding work instructions.. Their purpose is to explain in words and pictures the whole welding process for any production item.General Welding Guidelines - MCAAin the Welding Procedure Specification. When higher preheat is required by the applicable construction code (i.e. B31.1, B31.9, etc.), that preheat shall be used for production welding. Welding on metal that is wet is strictly prohibited; wet metal shall be heated until it
