It may be that the welding position is incorrect or there is a problem with the welding torch. At this time, to consider the TCP (welding torch center point) is accurate, and be adjusted. If this happens frequently check the zero position of each axis of the robot and recalibrate the zero to reset it.

(2) Undercut problem:

May be improper selection of welding parameters, welding torch angle or welding gun position is not right, need to be adjusted appropriately.

(3) The emergence of stomatal problems:

May be poor gas protection, the workpiece is too thick or not enough protective gas drying, the corresponding adjustment can be handled.

(4) Too much splash problem:

The improper selection of welding parameters, the reason of gas components or the extension length of welding wire is too long. The welding power can be adjusted by changing the welding parameters, adjusting the proportion of gas mixture and adjusting the relative position of welding torch and workpiece.

(5) The end of the weld after cooling to form a crater problem:

Programmable in the work step to add the function of buried crater, you can fill it.

Comparison of manual soldering and automatic soldering machine

The operation of the robot by the solder, determines its biggest advantage for the same welding products, solder joints, good quality and stability. At the same time for many products, one person operating a device efficiency can be achieved more than the efficiency of manual welding, with the advantage of improving efficiency. (But for some complex, not a fixed product, efficiency is not obvious)

Welding workers: As we all know, the welding process on the one hand requires the operator to have skilled operating skills, rich practical experience and stable welding level. The other hand, welding is a poor working conditions, smoke, heat radiation, risk High work. Welding is not the same as with other industrial processes, manual welding, experienced welders can be observed in accordance with the actual position of the welding seam in time to adjust the welding gun position, attitude and walking speed to meet the welding and welding trajectory Of the changes. So the work of welders is a certain technical content of the job, the factory, to recruit a skilled welders, workers on the current state of mind and the cost of the factory staff to become a positive and negative staggered opposing Situation, which is a bottleneck in hand soldering.

Welding process quality: the process of manual welding, welding workers by the level of the process limit, welding skills and uneven welding skills, mood swings have certain factors, the daily welding quality and yield of products and then be affected, This is the second bottleneck of manual welding.

Welding accessories costs: the skills and emotions of welding workers more or less used in welding accessories can not be estimated, how much to use to the warehouse to receive how many managers can not quantify the use of welding materials every day, that is, the cost of welding materials is A fuzzy concept, the production cost of the product is not quantified, the customer, for their own costs, is a can not say that the project, which is the bottleneck of the three manual welding.

Welding efficiency: the skills of welding workers, the efficiency of welding products every day is not to quantify the number of factories a day to produce the number of products, product quality is good. The so-called efficiency is obtained under what conditions? We understand that the purpose of welding is to obtain reliable solder joints! Therefore, the welding efficiency we require should be based on the premise of ensuring reliable solder joints; that is, while we are conducting high-efficiency welding, we should avoid a higher scrap rate as a cost.

Robot Soldering Machine

Soldering robot is a standard machine, after years of development of Japanese equipment manufacturers, have been stereotypes for the four-axis manipulator, five state manipulator. Equipped with automatic solder system, through the teaching box programming control of the shape structure. Soldering robot just can only complete the automatic soldering action,worker need to operation of the machine, with a fixture, through the preparation of a good program parameters in advance, worker put the products to clamp, and place a fixed fixture on the machine, then start the machine. Soldering robot in accordance with set the program operation, complete the welding work. Then worker removed the welding of good products, re-placed not installed welding products on machine to finished soldering, repeated again and again. So strictly speaking, soldering robot is a semi-automatic robot not a really full automatic robot.

Current Situation of Soldering Robot Market

Soldering robot, as the name suggests is a solder welding equipment, so in addition to mechanical hand movement function, the main thing is to complete the solder operation. So the core of the solder robot is the welding system. Solder system is mainly composed of automatic delivery of tin bodies and temperature control, heating elements, iron head.
