Many shops in Pune, Coimbatore and Bengaluru do all three in-house or through a tight local network, and deliver ready-to-install assemblies. ### What welding standards are used? Export shops typically qualify welders to ISO 9606 or AWS D1.1, and follow ISO 3834 or EN 1090 where required. ### What drawings should I send? Send 3D models, 2D drawings with tolerances and weld symbols, material specifications and finish requirements. More product guides ## Related products.
