Abstract
The magnetic field control method for electric arc welding is characterized in that, connecting in series or parallel around the welding line and generating another magnetic field with larger magnetic field strength than the existing to array the electric arc along magnetic contour of working field and form welding line. This invention fits to welding process with exterior disturbance, improves welding quality and decreases the requirement to welder.
Description
Technical field
The present invention relates to welding method, specifically is the method for arc welding.
Background technology
When arc welding is in magnetic field environment (as the Aluminum Electrolysis Production scene), welding arc can produce violent splashing under the effect in magnetic field, influence welding quality.If surrounding magnetic field is very powerful, even can cause the phenomenon that to weld.
The objective of the invention is arc welding successfully to be carried out by work magnetic field.
The present invention is the magnetic field control method that is used for arc welding, working site in existing magnetic field, around weld seam to be welded, coil (2) series connection or parallel connection with ribbon core, produce the work magnetic field of a magnetic field intensity again greater than existing magnetic field, welding arc is arranged along the magnetic line of force direction in work magnetic field, formed weld seam.
Coil (2), (2 ') in position to be welded with ribbon core are arranged in the next door for the treatment of welding line, the axis (OO ') of the coil of ribbon core (2), (2 ') is perpendicular to the plane at workpiece to be welded (1), (1 ') place, give coil electricity then, produce work magnetic field.
Coil (2), (2 ') in position to be welded with ribbon core are arranged in the next door for the treatment of welding line, the axis (OO ') of the coil of ribbon core (2), (2 ') is parallel to the plane at workpiece to be welded (1), (1 ') place, give coil electricity then, produce work magnetic field.
The coil of several ribbon cores (2), (2 ') couple together along the bead direction arrangement in weld seam both sides to be welded, give coil electricity then, produce work magnetic field.
In the manual electric arc welding occasion, when changing the welding position, the power supply in disconnection work magnetic field makes coil losing electricity, and manual moving coil, welds after the energising of work field coil to the next position that needs welding.
In automatic welding occasion, with coil stationary be installed in the welding wire end near.
The present invention is used for the welding process that external magnetic field disturbs, the work magnetic field that is provided has guiding and the stabilization to electric arc, be in the work magnetic field because of electric arc simultaneously, weldering is dropped in do not solidify before with its gas inside, welding slag discharge surface, improved welding quality, reduced requirement welder's technical merit.
The present invention also can be used to not have the welding process that external magnetic field disturbs, as vertical position welding, overhead welding occasion, or by irregular, the soldered spacing of welding line when big, the occasion of perhaps welding thin-walled material.
