“…Such work has already been carried out, and it has been proved that this technology requires a special approach [ 66 ]. Similarly, forcing the flow of air cooling the weld changes the heat transfer conditions during welding and requires taking this phenomenon into account when designing this technology [ 67 ]. It should be noted that in the case of the classical butt welding process of drive belts, conducted in the atmospheric air setting, the response of the material to the forced temperature change is more predictable and repetitive, and the resulting change in the material properties for both belt types is exhibiting a smaller difference.…”

The paper presents a comparative analysis of the circular and flat cross-section belts using measurements of a set of thermomechanical parameters, contributing to research about hot plate welding of drive belts. On the basis of thermogravimetric and spectrophotometric tests, information about the same chemical composition of the two belts was obtained. Dynamic thermomechanical analysis and scanning differential calorimetry provided information about a small difference between belts, which disappeared when the material was placed in a state of increased temperature and mechanical stress. On the basis of the analysis of the specific heat, thermal diffusion, density, and hardness, the values of the selected thermal properties of the belt were obtained, and a large similarity between the belts was identified. On the basis of the novel performed test cycle, it has been hypothesized that circular and flat belts made from thermoplastic polyurethane elastomer could be used interchangeably for butt-welding testing. It has also been proven that cyclic thermomechanical loads unify the properties of both materials so that multiple mechanical and thermal loads do not result in any change in the material properties of the two belts. As a consequence, changes in the weld properties after welding, compared to a solid belt, are not expected.

To complete the automatic heat sealing and inspection of a battery top cover, a new automatic heat sealing production line is designed in this paper. The production line is used to seal the upper and lower plates of the top cover and to test the related functions. The main purpose of the research is to improve the automation of the sealing and testing for this product. According to the working conditions and requirements of the company, the structure of the entire automatic heat sealing production line was designed through SolidWorks, and the operating principle of the key components were analysed. ANSYS was applied to carry out static analysis and thermal stress coupling analysis on the key components of the gripping and translating mechanism in the device to verify the rationality of its structural design.

“…Direkt birleştirme yöntemlerinden biri olan Sıcak Plaka Kaynağı (SPK), basit ve ekonomik oluşu nedeniyle diğer yöntemler arasında oldukça ilgi çekmektedir [2]. Sahip olduğu potansiyel bu yöntemin araç arka lambalarından, akü kutularına, yakıt tanklarından gaz veya sıvı iletim hatlarındaki borulara kadar uygulama alanı bulmasını sağlamıştır [19][20][21]. Bu yöntem genel olarak sırasıyla ısıtma, birleştirme ve soğutma aşamalarından oluşmaktadır.…”

Industrial demands of utilizing polymers and therefore, the search for more reliable joining techniques is gradually increasing. The use of Hot Plate Welding (HPW), which is one of the simplest and most economical methods of joining thermoplastics, is known to manufacture strong joints. This study reveals that it is possible to join LDPE and HDPE snugly using HPW method with appropriate parameters. In the research, similar and dissimilar polyethylene classes are joined with each other and mechanical properties of the joints are examined in terms of the tensile strength and impact behaviors. Obtained results are compared considering the base materials themselves and between
