In ship construction, welding is widely used and the most critical. Welding quality directly affects the cycle, cost and quality of ship construction.

In recent years, with the upward development of social economy, the younger generation has gradually "escaped" from the work intensity (different welding positions and types, operating posture or lying or squatting for a long time) and poor working environment (muggy, welding splash, generally need to wear heavy protective clothing) in the ship welding workshop, the age structure of skilled welders is deformed, and the average age is obviously on the big side. In addition, with the intensification of the high-end transformation of the domestic shipbuilding industry, enterprises naturally have higher and higher requirements for welding processes related to ship quality.

Customer demand

The customer is an "intelligent factory solution pilot demonstration" enterprise in the domestic shipbuilding industry, building and delivering more than 270 high-quality ships to global users, including bulk carriers, car carriers, super-large container ships, oil tankers, ore carriers, special ships, dual-fuel ships, etc., and has the reputation of "Super King of cargo at Sea" in the industry.

The volume of shipbuilding welding depends on the type of ship. In the ship orders undertaken by customers, medium and thick plates account for a relatively large proportion. In order to ensure the quality, "each weld requires dozens of welding procedures, and the qualified rate is required to reach 100% at the time of film inspection." Under such stringent quality requirements, the efficiency of traditional manual welding can not meet expectations. Customers hope to use automated, flexible and intelligent welding robots to improve welding efficiency while achieving stable and reliable welding quality. ensure timely delivery.

Large group robot scheme:

The Elfin series cooperative robot body is adopted, which is light in weight and can be carried / carried to any position in the welding workshop. It is easy to operate and can be quickly put into welding operation by dragging teaching or graphical programming. The repeated positioning accuracy is up to ±0.02mm, which meets the requirements of welding precision.

In the actual welding operation, the welder can easily complete the establishment of welding task, welding starting point, welding end point, welding start and other operations in the process of dragging through the end button of the mechanical arm, which is simple, convenient and efficient.

Compared with other cooperative robots, the large family robot series also has the following advantages, which make it more suitable for welding applications:

First, the mechanical arm structure which is more suitable for welding. The large robot adopts a unique double-joint module design, and a motion module contains two joints to form a unique kinematic structure, which can achieve higher flexibility in welding operations. Elfin-Pro series cooperative robot adopts inner wiring layout, and all welding can effectively avoid the problems such as limited motion range of manipulator and interference of communication signal caused by external wire harness winding.

Second, more convenient and efficient teaching operation. Elfin-Pro supports integrated end force control, which can easily achieve drag and drop with a drag force of less than 3N; help users easily and quickly drag the torch to the specified target solder joint, achieve accuracy and improve work efficiency.

Third, more open and suitable for all kinds of welding equipment. Clan robots can quickly adapt to mainstream welders at home and abroad, including Magmet, Loach, Otai, Binzel, Panasonic, Forness and Idaxin, etc. at the same time, it can effectively dock with manufacturers of robot vision and controllers specializing in the welding industry, and broaden the choice of customer products.

Adhering to the mission of "serving the people with robot technology", ethnic robots continue to polish and optimize the welding process package to make the welding operation simpler and more efficient. At the same time, large robots also have the advantages of "arc tracking", "laser visual seam tracking" and "multi-layer multi-pass welding" in the welding field.

Effect evaluation:

Double improvement of quality and efficiency, saving manpower: according to the person in charge of the customer's workshop department, under the normal operation of all the equipment, one ordinary welder can operate four welding robots at the same time, and the working efficiency has been greatly improved. compared with traditional manual welding, the welding quality is more stable and reliable, and the finished product is more consistent.

It is helpful to further improve the intelligence level of the welding workshop: it is the development trend of the industry to strengthen the application of welding robot in the field of ship construction. With the help of large family robots, the proportion of welding robots in customer segmented production workshops has gradually increased, and the level of welding automation and intelligence has improved steadily, which can enable customers to maintain a leading position in the increasingly competitive shipbuilding field.

The deep integration of welding robot and ship construction can greatly improve the production efficiency and automation level of shipbuilding and repair enterprises. Large group robots will continue to dig into the unique advantages of cooperative robots in ships and other welding fields, and provide users and partners with robotic arm products that are more suitable for welding.
