Cooperation can realize that X axis is mobile by protective housing top winding guide rail after the completion of cooperation, so as to neatly to needing to heat
Position carry out local heating.It is by load coil come directly to steel column since electromagnetic induction welds its technical principle
(welded workpiece) surface directly heats, and the water meeting flash evapn vaporization on steel column surface, the vapor constantly generated can be in steel column
Surface forms one layer of fine and close steam blanket, and steel column and seawater are completely cut off, to form one piece of anhydrous region of approximation outside steel column.
While steam blanket isolation seawater avoids seawater from directly cooling down to steel column, moreover it is possible to reduce the loss of heat, guarantee heating efficiency, contracting
Short heating time.The end to be welded of steel column is machined with 45 ° of chamferings, after the completion of to be heated, carries out extruding welding at once, at this time workpiece
Surface steam blanket still remains, and steel column outer surface is kept apart with seawater, greatly reduces commissure and generates oxidation and liberation of hydrogen etc.
Welding defect, and since the presence of steel column end chamfer to be welded, two steel columns will form the slot of 90 ° of outward openings when contacting, it squeezes
The metal structure that face of weld has the welding defects such as stomata oxidation on a small quantity in welding process also can be as opening direction be outside
It is extruded into flash, substantially increases commissure structure property.When the welding is completed, as steel column surface temperature reduces, steam
Film fades away, and seawater is directly quenched with bead contact at this time, improves face of weld hardness.Then commissure is added again
Heat carries out annealing heat-treatment, and steam blanket generates isolation seawater, completion to be heated again, and seawater again quenches commissure,
It refines commissure and organizes crystal grain, improve commissure structure property.
