Guide for Welding Mild Steel Pipe

AWS D10.12M/D10.12 – Guide for Welding Mild Steel Pipe

The “mild steel” in this new AWS standard refers to low-carbon (less than 0.25%carbon) steels such as ASTM A 53, A 106, A 135, A 179, A 524, A 587, and API-5L,Grades A25, A and B, and X42. Pipe sizes to be welded using the procedures of Guidefor Welding Mild Steel Pipe (D10.12M/ D10.12:2000) are those not greater than DN 200(NPS 8) maximum, will wall thicknesses up to 13 mm (0.5 in.) maximum.

Examples of applications where D10.12M will be particularly useful are piping systems such as:

• Low pressure heating
• Air conditioning
• Refrigeration
• Water Suppliesas well as some gas or chemical systems.

Welding techniques for procedures such as

• Preheating
• Joint preparation
• Alignment and positions
• Fittings
• Root and hot passesare provided for SMAW, OAW, GTAW, and GMAW.
