Abstract
The invention discloses a method for carrying out pre-welding treatment on a welding rod for welding a cabin cover. The method comprises the steps of: (1) drying the welding rod; (2) placing the welding rod which is subjected to drying treatment onto a cover of a welding rod insulating box barrel; (3) putting the welding rod onto the cover of the welding rod insulating box barrel for no more than 5 hours; if the time is more than 5 hours, carrying out the drying treatment on the welding rod again; (4) carrying out the drying treatment on the welding rod for no more than 3 times. Furthermore, the time for drying the welding rod is 1 hour. The method for carrying out the pre-welding treatment on the welding rod for welding the cabin cover disclosed by the invention can effectively control the water content of the welding rod; in a process of welding the cabin cover, an air pore is not formed in a welding line, so that the quality of the cabin cover can be improved.
Description
Technical field
The present invention relates to a kind of welding rod, be specifically related to the method for a kind of pre-welding treatment welding hatchcover with welding rod.
Background technology
Boats and ships are general names of various ships.Boats and ships are can navigate by water or berth in waters, to transport or the vehicles of operation, by different instructions for uses, have different technical performances, equipment and structural shape.The hatchcover of boats and ships is by top board, moulding bed, crossbeam, floor, side plate, base plate, and assembled being welded such as end supports.Therefore, in the process of making hatchcover, need a large amount of welding rods.The quality of welding rod directly can affect the quality of hatchcover.
When welding rod was gas welding or electric welding, fusing was filled in the bonding jumper of the joint of welding work pieces.The material of the welding rod material with workpiece usually is identical.Welding rod is by coating and metal-cored composition of being coated by coating, the metal-cored core wire that is commonly called coated by coating.
Core wire is generally a steel wire with certain-length and diameter.During welding, core wire has two effects: the one, and the conduction welding current, produce electric arc the electric energy energy transform into heat energy, and the 2nd, core wire fusing itself forms weld seam as filling metal and the fusion of liquid base metals.During the welding rod welding, the core wire metal accounts for the part of whole weld metal.So the chemical composition of core wire, directly affect the quality of weld seam.For quality and the performance that guarantees weld seam, the content of each metallic element in core wire is had to strict regulation, particularly to the content of objectionable impurities (as sulphur, phosphorus etc.).
At present, in welding hatchcover process, commissure occurs often pore, and this pore has reduced the mechanical performance of weld seam, even can cause weld seam generation crackle, thereby greatly reduces the quality of hatchcover.Therefore, how avoiding commissure that pore is arranged is that one of technical problem to be solved is arranged.
Summary of the invention
For solving in welding hatchcover process, the leachy technical problem in commissure, the invention provides the method for a kind of pre-welding treatment welding hatchcover with welding rod, to improve the quality of hatchcover.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of pre-welding treatment welding hatchcover, by the method for welding rod, comprises the steps:
(1) dry welding rod;
(2) welding rod of drying being processed is placed on the lid of electrode thermostat container cylinder;
(3) time of being placed on the lid of electrode thermostat container cylinder of welding rod should be over 5 hours; If surpass 5 hours, need welding rod is carried out to drying and processing again;
(4) described welding rod carry out the number of times of drying and processing must not be over 3 times.
Further, the time of oven dry welding rod is 1 hour.
By technique scheme, the method for hatchcover with welding rod welded in a kind of pre-welding treatment provided by the invention, can effectively control the water content of welding rod, and in welding hatchcover process, commissure not there will be pore, thereby can improve the quality of hatchcover.
The specific embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described.
A kind of pre-welding treatment welding hatchcover provided by the present invention, by the method for welding rod, comprises the steps:
(1) dry welding rod;
(2) welding rod of drying being processed is placed on the lid of electrode thermostat container cylinder;
(3) time of being placed on the lid of electrode thermostat container cylinder of welding rod should be over 5 hours; If surpass 5 hours, need welding rod is carried out to drying and processing again;
(4) described welding rod carry out the number of times of drying and processing must not be over 3 times.
As the further improvements in methods of a kind of pre-welding treatment welding hatchcover provided by the invention with welding rod, the time of drying welding rod is 1 hour.
The method of hatchcover with welding rod welded in a kind of pre-welding treatment provided by the invention, can effectively control the water content of welding rod, and in welding hatchcover process, commissure not there will be pore, thereby can improve the quality of hatchcover.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. the method for hatchcover with welding rod welded in a pre-welding treatment, it is characterized in that, comprises the steps:
