the purpose

- Want to reduce the amount of work required to deal with distortion and weld burns after welding

- We want to achieve a higher quality finish by minimizing damage to the thin plate.

assignment

- Distortion and welding burns occurred, which had a significant impact on finishing effort and quality.

effect

- Significant reduction in post-processing work allows for a smooth transition to the painting process

- Welding that minimizes the effects of heat eliminates damage to the backside, resulting in more stable quality.

About Yashima Control Systems Co., Ltd.

Yashima Control Systems Co., Ltd. delivers control panels to public facilities and private facilities throughout Japan. A control panel is a box that controls automatically operated machines and equipment. It is the power source that moves things and plays an essential role in our lives. As a manufacturer, Yashima Control Systems Co., Ltd.'s strength is that they not only produce control panels, but also provide customers with peace of mind and safety through a consistent response from sales and design to system construction, sheet metal painting, inspection, on-site modification work, and maintenance. Since all products are made to order, they can flexibly respond to customer needs that are not available in standard products, such as control panels that can be stored in dead spaces and painting to match the image color.

Yashima Control System Co., Ltd. uses our stud welding machine when welding the back side of the door of the control panel. We will introduce the situations in which they use it and the benefits.

Reason for introducing CD stud welding machine

■Products used
CD stud welding machine CDi-1502, CDi-2302
■ Issues before implementation
Post-welding processing time

Yashima Control Systems Co., Ltd. considered introducing a stud welding machine to reduce the amount of work required during and after welding. The back side of the door of the control panel is where the bolts are welded and pockets and filters are attached. If the bolts are attached by hand welding, distortion and welding burns will appear on the back side of the welded work. After welding, the distortion and welding burns must be polished off before painting can be performed, but if welding is performed with a stud welding machine, there is almost no post-processing work required and it is possible to move on to the painting process.

Advantages of introducing CD stud welding machines

■ Usage
Welding the back side of the control panel box door
■ Advantages
Reduced man-hours due to reduced distortion and welding burns, compact and powerful

When welding the back of the doorDistortion and welding burns are less likely to occur.This eliminated the need for subsequent processing, leading to a reduction in lead time. Furthermore, Yashima Control Systems Co., Ltd. places great importance on quality and safety during manufacturing. For this reason, it is extremely important that the finished product has a beautiful appearance and that the dimensions are within the drawing tolerances. Quality has also improved as there is no longer distortion due to welding and the need to polish weld burns has been reduced. The CD series isSupports plate thickness up to 6mmThis means that even thin plates are less likely to develop distortion on the back side.

In addition, the HBS stud welding machineCompact, weighing approximately 15kg per unitTherefore, it is easy to carry around. Yashima Control Systems Co., Ltd. uses two units, one of which was purchased to take with them on business trips.

■ Welding process

The welding machine and bolts are stored on a dedicated stand.

■ Back of door after welding

Install the filter behind the door.

Screws are attached using stud welding to install the document holder.

Yashima Control Systems Co., Ltd. is working to strengthen its environmentally friendly manufacturing. "Environmentally friendly and trustworthy products" are also "people-friendly in the manufacturing process."
For this reason, riveted assembly frames are being promoted when processing metal plates that will become control panel boxes. Until now, processing was done using CO2 and TIG welding, but assembly by welding generates chemical welding fumes and dust when polishing weld burns, which can have adverse effects on the human body. The riveted assembly frame used instead does not use heat, so no fumes or dust are generated, and distortion is less than with welding, which also leads to improved quality.
We will do our best to contribute even a little to the manufacturing of Yashima Control Systems Co., Ltd.
