Techshore Institute of Welding Technology is an initiative of the leading professional & reputed training brand of Techshore Inspection Services, which is having training centres all over Kerala. Techshore, offers courses in Welding Technology from early 2015 and successful in providing placements for all those candidates in reputed companies with attractive salary packages and perks.
Welding Procedure Specification
A welding procedure specification (WPS) is the formal
written document describing welding procedures, which provides direction to the
welder or welding operators for making sound and quality production welds as
per the code requirements. The purpose of the document is to guide welders to
the accepted procedures so that repeatable and trusted welding techniques are
used. A WPS is developed for each material alloy and for each welding type
used. Specific codes and/or engineering societies are often the driving force
behind the development of a company’s WPS.A WPS is supported by a Procedure
Qualification Record (PQR OR WPQR). A PQR is a record of a test weld performed
and tested (more rigorously) to ensure that the procedure will produce a good
weld. Individual welders are certified with a qualification test documented in
a Welder Qualification Test Record (WQTR) that shows they have the
understanding and demonstrated ability to work with in the specified WPS.
A welding inspector is an individual who is responsible for overseeing all the activities and duties of the welding staff and ensuring that everything is in proper working manner. Quality control inspectors: read and understand blueprints and specifications. Monitor or observe operations to ensure that they meet productions standards...Inspect, test, or measure materials or products being produced. Welding procedure Specifications, building and welding plans, equipment calibration, and welding materials. You'll be responsible for verifying that all of those documents are correct. You'll also be instrumental in the development of WPSs. It'll be your responsibility to inspect base and consumable materials. What does a certified welding inspector do?? Many welders start out without any long-term career goals...The AWS Certified Welding Inspector(CWI) certification is an internationally recognized accreditation that can open the door to a highly rewarding and lucrative
profession.
Visual inspections of Welded
Connections
Visual
inspections is probably the most underrated, and often misused, method of
welding inspection. Because of its simplicity, and the absence of sophisticated
equipment, the potential of this method of inspection is quite often under-
estimated. Visual inspection of welding can often be the easiest to perform and
is usually the least expensive to conduct. If carried out correctly, this type
of inspection can often be an extremely effective method of maintaining
acceptable welding problems. There are many areas with in the welding operation
that can be verified and evaluated by this method of inspection.
When designing an inspection plan,
we need to establish the most appropriate areas to apply out inspection. We
need to consider the possibility of preventing welding related occurred. Non- destructive
testing (NDT) , which is typically used for the inspections of completed welds,
is usually designed and conducted to find welding problems after the fact, when
the weld is completed. Visual inspection can often be utilized to prevent
welding problems from happening in the first place. The welding inspection
function is often divided into three areas. First, and often the least utilized
is pre-weld inspection can often provide us the opportunity to detect and
correct unacceptable conditions before they develop into actual welding
problems. Second, inspection during the welding operation can often prevent
problems in the completed weld through verification of the welding conditions
and procedural requirements. Third, post welded visual inspection is a
relatively easy method of conducting completed weld quality evaluation.
