We would see about Recommendations for Welding of Structural Steel as per AWS D1.1 , 2020 revision
Groove Weld: (Clause 4.4.1)
Weld Length : shall be the width of the parts joined , perpendicular to the direction of compressive or tensile stress,
Weld Size: Thickness of thinner…
The sole purpose of welding procedures is to describe the details that are to be followed in the welding of specific materials or type of joint. The following is a list of standard specifications for welding procedures that are normally covered in welding procedures…
Positions for Welding Pipe
For welding pipe in shops, power plants, oil refineries, and chemical plants for crude oil, gasoline, and natural gas, the same basic welding positions described previously are used.
Flat Butt Weld Pipe Position…
Fillet Weld Positions
The advantage of the fillet-welded joint is that it’s unnecessary to prepare the edges of the plates or sheets for welding. Double fillet-welded joints are an improvement over single-fillet joints because they can withstand loads from more than one direction.
Three of the…
Standards for Welding Positions:
It is very important for the Weld Inspector to know the position, or location of a joint relative to the horizon, because it may determine what welding process, methods, and techniques can be used.
Welding is usually easiest when the welder can…
Types of Welding
Welding process involves joining of two metals and sometimes non-metals such as plastic
There are many different types of weld, as below:
Atomic Hydrogen Welding ( AHW)
Bare Metal Arc Welding (BMAW)
Carbon Arc Welding (CAW)
Electro Gas Welding (EGW)
Welding Procedure Specification- WPS
This document details, how to qualify a welding procedure specification-wps for weld metal overlay / cladding / surfacing , for both corrosion resistance overlay and wear resistance overlay welding.
The reference standard selected for the purpose of qualification of cladding procedure and…
TASKS DURING WELDING OPERATIONS
Welding inspection during welding operations should
include all the audit parameters to verify that the welding is performed to the procedures. Such tasks may include the following:
Establish a quality assurance and quality control team
with the welding organization.
Quality control items to assess:
Welding is a process of joining metals by process of heating. Most of the weld made are manual. It is possible that the weld may have various defect formation due to parameters of welding and poor workmanship.
Why is Welding Inspection Methods important?
Therefore the weld…
What is welder qualification test?
Welder Certificate is a document that shows ability of a welder to make a quality weld in a particular welding process.
The Certificate also denotes on which type of welding material and…
