How can electric welding be done perfectly?
Flat welding in the case of thick solder can be welded, pay attention to the welding, welding treaty is 70- 80 degrees.Don't move too fast. Keep your speed steady.After welding a electrode, remove the last centimeter of electrode, overlap ignition 5mm, return to the welding straight forward.Vertical welding: must from the bottom up welding, spot welding, pay attention to the spot welding time, from the bottom up firmly connected.If it's a corner joint, it must be on fire and cease fire.That can be firm.
First of all, when it comes to vertical welding, first of all, in the positioning of welding, carry out inverse positioning, leaving a larger gap, the Angle between the electrode and the iron plate is about 60 degrees, the bottom welding of the current is slightly larger, the use of double-click method, withstand X-ray inspection, a little behind The Times.Click the method must be closed arc vertical arc stability, eyes, spot welding must be correct, to ensure the first bottom cutting welding, welding highest!The second time is the cover.This is plate to plate welding with one side and two sides forming.Using the double-point method, not only for the flat welding, but also for the vertical welding and back welding (80 degrees), welding the most important thing is to protect yourself, using a wallet and canvas or jeans, more heat resistance, more clear, hand stability, accurate, I always use the arm hanging brick practice arm began to learn paper cutting practice, waiting for you to remember.Other welding methods are not all the same.
The following manual arc welding, beginners to master the operation:
1, the molten iron and slag, molten pool shape and molten depth can be clearly distinguished.
2. How much current is used in the welding rod? How to adjust the current with the welding machine?
3. Welding mode and electrode Angle at various positions.
4. Master the weldability, welding characteristics and electrode selection of workpiece with different materials.
5. Form and preventive measures of welding deformation and corrective methods after deformation.
6. Understanding of general welding process and recognition of welding symbols.
7. General knowledge of metal materials.
Upper secondary grasp:
1, - unit welding theory, welding machine working principle and general fault handling.
2, prepare the general workpiece welding process and procedures.
3. Master single-sided welding double-sided forming technology and general welding skills of non-ferrous metals.There are too many types of welding negotiation, and the marginal disciplines of negotiation are very extensive. In short, it looks simple to enter the door, but in fact, it is not refined.Operation, only do after practice difficult, from there to summarize experience, concentrate on the words will succeed!In fact, to practice, to think, to read more books on the subject,
Mainly by personal summary!Find a good teacher to actually teach, even better.It is not realistic to improve technology only by theoretical explanation!Give priority to with the worker practice, with the theory is auxiliary, especially the technology is better, the theory foundation that asks for is better!
