1. Welded tube information

● Tube diameter: 19-60mm (if more then 60mm then extend the disc and slot)

● Tube wall thickness: 2-5mm

● Tube material: carbon steel, stainless steel

● Welding situation: full welding (tube and sheet in same level or tube stretch out)

2. Pre-weld cleaning and requirements

● Pre-weld cleaning and require special tools before welding to polish the outside of the tube end 20mm, revealing the metal color, rust removal on the surface of the tube plate

● In order to facilitate the positioning of the locator, in the tube hole to remove burrs

● Wash the surface oil of the work-piece with acetone or alcohol

● Work-piece spot welding with manual argon arc welding without wire, solder joints to be welded in the groove inside, do not weld the tube mouth

● If it is the first to rise after the welding process, in the tube can not use grease and other lubricants

● When welding angle weld, tube outstretched range: 3-5mm

● Standard 99.99% argon is recommended when no special requirements are available

● Argon airflow is controlled at 5-8L/min when no special process requirements are required

● The assembly gap between the tube and the board shall be uniform, and the unilateral clearance shall be controlled within 0.5mm
