Welding of Pipes and Fittings what you need to know about

Welding is an essential piping manufacture action. It is basic to guarantee fantastic welds to guarantee safe plant operation. Different strategies are utilized to ensure the welds are of most astounding quality, for example, alluding best universal gauges, making affirmed welding capability techniques and so forth.

In process industry, most generally utilized codes are :

ASME Codes, for example, B31.1, B31.3, B31.4, B31.8 and so forth.

ASME Boiler and Pressure Vessel Code.

A few nations have their own neighborhood codes pertinent to specific frameworks, for example, in India, steam piping must affirm to IBR controls.


Regularly in hydrocarbon industry, carbon steel, composite steel and stainless steel are the base materials to be welded. Extend welding detail is an essential record that must be alluded by welding temporary worker while doing his work. This determination incorporates every one of the necessities of welding for the specific venture.

Shop Welds and Field Welds

Piping isometric drawing is set apart with shop welds and field welds. Shop welds are favored however much as could be expected as weld quality can be firmly controlled in shop. Be that as it may, greatest transportable spool estimate must be considered and also any field bungle of measurements.



Weld MTO

Weld MTO is indicated in inch-dia which is number of welds increased by pipe diamter.

Welding Consummables

Welding consummables incorporate anodes, filler wires, argon gas and so on. Nature of welding consummables must be guaranteed according to venture welding determination. Regularly argon gas is required to be of 99.995 percent virtue.

Capability of Welders

Welders must be qualified according to relevant code e.g. B31.3

Welding Contractor's Scope of Work


All the welding gear like transformers, thermocouples, pyro-meters, programmed temperature recorders, warm treatment equipmets and so forth is given by welding contractual worker. All the weld testing hardware like radiographic types of gear, radiographic movies, darkroom offices, color penetrant testing, attractive molecule testing, ultrasonic testing and so on are given by the welding temporary worker.

Welding Processes

By and large utilized welding procedures are SMAW and GTAW.

SMAW : Shielded Metal Arc Welding Process

GTAW : Gas Tungsten Arc Welding Process

Which welding procedure to be emplyed where is given in Project Welding Specification.

Look at these recordings from youtube to observe of these techniques.
