Sanitary Fittings few problems in the welding process
About one-side welding without backing, the importance of the shortcomings and lack of penetration welds agree about. Important not weld penetration does not allow one side; more important weld penetration promised to end the presence of the depth of not more than 10% to 15% of the thickness of the base material (depending on the weld grades may be), and shall not exceed 2M, not welded through the same level does not exceed the length of the weld slag promised total length; usually end weld penetration depth should be less than 20% the thickness of the base material, and does not exceed 3mm, length should be less than the total length side promised folder.
To avoid mixed with other slag, should be strictly finishing stainless steel tube base metal groove and dirt, oxide slag neighboring appearance, before completely finishing a weld slag.
For the stainless steel pipe fittings abundant slag floats, to pick moderate welding current, the bath temperature must reach to avoid the weld metal cooling too quickly.
Proficiency skills, and always maintain melt him clearly visible, promoting separation of slag and molten iron outstanding.
The use of a neutral gas welding flame, the operator will use the wire outgoing slag bath.
