According to the defects of titanic alloy, which are easy togenerate crack, blowhole, embrittlement, the article introduces welding experience of three sets of titanic alloy filter in water treatment unit in a project. To adopt argon tungsten pulsed arc welding, to select rational parameter of welding technology and heat treatment temperature, and to grasp the main operation point in welding construction, the project achieved success. All sets of filter have not been found any abnormal and corrosion sign for one year applying.
