Welding till the End!
In this article we have discussed about the difference between welder and welding operator, purpose of their qualification and how ASME section IX divided the welding in manual, semi-automatic, machine and automatic welding.
In this article we will discuss about the Supplementary Essential variable for GTAW, SMAW, SAW and GMAW welding process as per ASME BPVC Section IX for qualifying a groove weld PQR (Procedure Qualification Record). What is supplementary Essential Variable? A supplementary essential variables are those variable in which change will affect the toughness property of
Navigating an interview as a Welding & Quality Engineer demands both technical expertise and clarity of communication. This article gathers high-impact questions that are likely to surface during interviews for welding and quality-focused roles—designed to help you anticipate what’s asked and answer with confidence. From complex metallurgical concepts like delta ferrite and P91 procedure welding,
The ASME Section IX specifies the requirements for the qualification of welders, welding operators, brazers, brazing operators, and fusion operators. It also governs the qualification of procedures employed in welding, brazing, and plastic fusing in accordance with the ASME Boiler and Pressure Vessel Code (BPVC), ASME B31 Code for Pressure Piping, and other related codes
In this article we will discuss about the tube to tubesheet welder and welding operator qualification as per BPVC ASME Section IX. Tube to Tubesheet Welding Tube to tube sheet welding is a special kind of welding, both process and technique wise. Essentially the parameters, techniques adopted for a groove weld will not work for
This article will cover the essential mechanical testing procedures outlined in ASME BPVC Section IX (ASME section 9)for the qualification of a groove weld PQR (Procedure Qualification Record), including details on specimen extraction location, the objectives of the testing, and criteria for acceptance. Testing Requirement: QW-451 outlines the specific type and quantity of test specimens
What is Heat Input (HI): In arc welding, energy is transferred from the welding electrode to the base metal by an electric arc. When welder initiate the arc, the welding electrode and base metal is melted and weld pool is generated. This weld pool results due to the energy supplied through the power source. Energy
This article is about Welding Position involved in fabrication of Pressure Vessel, Piping and Pipelines. Different welding standard specifies different welding positions for welder. Welding position is specified as per the position of work piece before and during welding. Position of welding is specified in ASME section IX and EN ISO 6947. Welding position is
