FAQ
After we develop and qualify the welding procedure specification we need to capture this information on record, the document used for this is called a welding procedure qualification record. WPQR, after qualifying the WPS, each welder required to weld on the project shall be tested and qualified on the procedure, this info is also required to be captured after the welder successfully pass the relevant testing criteria on a Welder Performance Qualification Record (WQR) form.
We develop and qualify a welding procedure specification to ensure that the deposited weld on the weldment are made satisfactory ensuring adequate material fusion and adherence to stated quality requirements.
A company which is certified as a ISO 9001:2015 company, has proven that it conducts its business activities based on internationally recognised practices/processes and could present evidence as well as traceability of all the required processes from recieving a enquiry up to the point of manufacturing and ultimately the execution and completion of the product it supplies to various clients / industries.
When a company decides to weld according to international standards then there are various codes that are required to be followed based on various essential variables such as the welding process, weldment material, welding positions etc. The widely most used codes are written in accordance with ASME & AWS.
Some of the code requirements as outlined above are various testing methods to ensure adequate weld quality, namely Non Destructive Testing comprising of RT (radiographic testing of the weld metal - X-Rays), UT (ultra sonic testing of the material by utilising sound waves), PT (Liquid penetrant testing - identifying surface defects)
Corrosion could usually affect material strength and properties as well as its appearance which is then required to be addressed, the most widely used process utilised for this is sand blasting as it is cost effective as well as one of the best methods used to remove corrosion from surfaces.
When we apply welding onto some materials, the heat generated from this will affect the material composition and its specific grain structure which could if not addressed have disastrous consequences on the affected weldment. Due to this it is often required to conduct pre-heating activities & post weld heat treatment as and when required in line with the relevent code or standard.
Corrosion protection involves the protection of surface material from any corrosion such as rust, this is usually addressed by applying paints, epoxies or some kind of surface protection covering the metals surface and protecting it from various elements which could affect the metal
Rigging studies are drawn up by the rigger performing the required lifting exercise, this is to ensure that the various planning regarding the specific lift as well as the relevent safety requirements are addressed and that these measures are in place prior to performing the lift.

Lifting machinery / equipment are being load tested at 110% of its rated capacity on an annual basis as outlined in the driven machinery regulations within the OHS Act 181 of 1993, this is to ensure that the said equipment can be safely utilised.
