Abstract
The invention discloses a welding method of a flat-bulb steel butt joint. The welding method is characterized by comprising the following steps: clearing rust and greasy dirt on the surfaces of two end parts of a joint to be welded and then butting the cleaned joint to be welded at an interval of 3 mm-5 mm; then, pasting a ceramic gasket on one surface of the butted part, and forming a V-shaped groove of 48-52 degrees in the end opening of the other surface of the butted part, selecting an alkaline welding bar with a corresponding diameter according to the size of a workpiece, regulating the welding voltage and current, and welding the groove. According to the welding method disclosed by the invention, the ceramic lining is pasted on one surface and single-surface welding is performed on the other surface, so that the operation is simple and convenient, the welding quality is good and the production efficiency is high.
Description
Technical field
The present invention relates to a kind of metal solder technique, particularly a kind of flat-bulb steel banjo fixing butt jointing welding method.
Background technology
The material of flat-bulb steel Chang Zuowei hull, close up the stage hull is little, the welding of flat-bulb steel often adopts the way of being stood up by hull to carry out two-sided welding, in hull, closes up the stage greatly and then hull cannot be stood up welding, affect Ship Structure quality.
Summary of the invention
The object of this invention is to provide one only needs single-sided welding to ensure welding quality, and production efficiency is high, flat-bulb steel banjo fixing butt jointing welding method easy and simple to handle.
The concrete welding method that the present invention adopts is: first the rusty stain on surface, joint both ends to be welded, the clean rear interval 3mm ~ 5mm of oil removal are docked, then pasted with ceramic veneer liner in the one side of joint, the V-butt of 50 ° ± 2 ° is increased in the port of joint another side, select the basic electrode of respective diameters according to workpiece size, adjustment weldingvoltage, electric current implement welding for groove place.
The present invention is owing to adopting above welding method, and in one side, pasted with ceramic veneer liner, another side implements single-sided welding, easy and simple to handle, and welding quality is good, and production efficiency is high.
Detailed description of the invention
First the rusty stain on surface, joint both ends to be welded, the clean rear interval 3mm ~ 5mm of oil removal are docked, then pasted with ceramic veneer liner in the one side of joint, the V-butt of 50 ° ± 2 ° is increased in the port of joint another side, select the basic electrode close with band steel joint material of respective diameters according to workpiece size, adjustment weldingvoltage, electric current implement welding for groove place.The present embodiment for 4mm, selects core diameter 2.5mm, weldingvoltage 24V ~ 26V, welding current 60A ~ 80A for welded blank thickness.
