DV Training Services Pte Ltd is providing the one stop solution for the marine and shipyard industry work permit holders. We are providing safety courses as well as Shipyard Low levy training & test.

Now, new upgraded facility can accommodate more welders and training can be done simultaneously with different welding process. Different materials can handle in this upgraded facility For piping, CS, SS and CUNI materials and structure CS materials.

Shielded Metal Arc Welding (SMAW)

Gas tungsten arc welding (GTAW)

Flex Cored Arc Welding (FCAW)

The Welding Procedure Specifications (WPS) is created to ensure the repeatable acceptability of the weld when the procedure is executed by trained and qualified professional welders. The advantage of computer-assisted processes is in making sure that essential, supplementary essential and non-essential variables are being followed, fulfilling the requirements of the code being used, ASME Section IX, AWS D1.1, API 1104, or any other.

purpose of Welding Procedure Specifications

DV Training providing the consultancy services to prepare the Welding Procedure Specification (WPS) accordance to the client requirements. The package is including the followings

A Welding Procedure Specification (WPS), is a document that serves as a guide for the effective creation of a weld that meets all applicable code requirements and production standards. WPS is a primary source for welders to refer before commencing their job. They must comply those parameters mentioned in the wps.

A Procedure Qualification Record (PQR) is the record of the actual weld test parameters used. It is the founding document as far as procedures are concerned and is used to produce welding procedure specification sheets (WPS) for production welds.

The WPS is written by welding engineer and needs to be mechanical tested to ensure the produced weld has required mechanical property. Before commencing the PQR Welding ensure all the equipment’s are calibrated and power sources connected properly, during welding record actual parameters as per approved “Proposed WPS”, this parameters need to be transfer to WPS for production welding

The completed weld coupon has to NDT tested before sent out to Mechanical test which is required to proven the mechanical properties such as strength, ductility etc. Please note WPS comes with the range, but PQR having actual records only. All the variables mentioned in the WPS must comply during production welding. All this variables must comply with international codes such as AWS D1.1, ASME Sec-IX, BSEN standards and client requirements

DV Training providing the consultancy services to prepare the Procedure Qualification Record (PQR) accordance to the client requirements. The package is including the followings

This Welding process is relevant to operators, technicians and supervisors across all process sector, to carry out plate wielding using 3G SMAW or 4G SMAW.

Through this theory session we will make the trainees understand about review maintenance documentation and technical manuals to determine required tasks

Prepare parts for welding in accordance with material specifications and job requirements, Select the type of welding to be used in the repair process

Check for distortions and measure components and parts to verify conformity with job specifications, Identify Properties of weld metals affect the weldability

Identify defective welded parts by visual examination and workshop tests and take corrective actions to address the causes of weld faults, Adhere to technical manuals and organisational procedures.

Process required maintenance documentation in accordance with regulatory requirements.
