2.Welders training and certifications

We can appreciate the importance of theoretical as well as practical inputs for a reasonable time period(7weeks) to make a useful welder both qualified and skilled.Many countries follow standards which give very useful guidelines to conduct training programme effectively.Only qualified and certified welders need to be employed as per respective codes for product manufacture.There is lot of demand for such welders for plate and pipe welding applications.As some of the products are very critical due to  stringent service requirement ,welders should be trained as per specific job needs. Pressure vessels manufacture involves both shop floor and site fabrication.Many materials as well as welding positions makes the training more involved and instructors face many challenges.They require good competence. Welders put on the job should satisfy quality requirements and must exhibit enormous skills as the joints should pass NDT tests and meet service specifications. During training period the welders should acquire sufficient knowledge on theoretical aspects and also practice as per instructions.Week after week their performance should improve and only fit welders are allowed to appear for testing before authorised approval body.After certifying only they are allowed to weld on the job.Recertification is mandatory after a stipulated period. IS 817 gives complete details for shielded metal arc training. In the USA ,AWSD1.1,ASME sec IX,API 1104 are generally used for welder certification.Some companies in addition may specify their own standards . In Europe EN  ISO 9606-1(EN 287-1) is used for welders testing of fusion welds in steels. Typical training guidelines from world reputed organisations are given below for reference. Typical competency for SMAW welders Line (GAC): D Shielded Metal Arc Welding (SMAW) Competency: D6 Use the SMAW process on low carbon steel plate and pipe Objectives To be competent in this area, the individual must be able to:  Use the SMAW process to weld groove welds on low carbon steel plate and pipe.
