Introduction
1. Standard Overview
GB/T 33209-2016 "Welding Procedure Qualification for Welded Gas Cylinders" is a Chinese national standard that aims to standardize the welding procedure qualification process for welded gas cylinders. This standard is applicable to various welding methods for welded gas cylinders made of carbon steel, low alloy steel, austenitic stainless steel, ferritic stainless steel and austenitic-ferritic stainless steel, including arc welding, submerged arc welding, gas tungsten arc welding, gas metal arc welding and plasma arc welding.
2. Background of Standard Formulation
With the development of industry, gas cylinders are increasingly used in various fields. The safety of welded gas cylinders is directly related to the safety of people's lives and property and social stability. In order to ensure the manufacturing quality of welded gas cylinders, it is particularly important to standardize their welding procedure qualification process. This standard is formulated based on international advanced experience and combined with China's actual situation, aiming to provide a scientific and technical basis for the gas cylinder manufacturing industry.
