    Abstract: The invention concerns a method of welding two metal parts together. The first part and the second part are made of metal or metal alloys and the reflectivity of the first part is lower than or equal to the reflectivity of the second part. Typically the first part is made of brass and the second part is made of copper. In the common welding zone, the less reflective part covers the most reflective part, so the laser beam is directed only against the less reflective part. The advantage of this is that the laser beam is not directly in contact with the high reflective part so less energy is reflected away from the welding zone.

    Abstract translation: 本发明涉及将两个金属部件焊接在一起的方法。 第一部分和第二部分由金属或金属合金制成，第一部分的反射率低于或等于第二部分的反射率。 通常，第一部分由黄铜制成，第二部分由铜制成。 在普通焊接区域中，反射较少的部分覆盖最反射部分，因此激光束仅针对反射较少的部分。 其优点是激光束不直接与高反射部分接触，因此较少的能量被反射离开焊接区域。

    Abstract: A thermal expansion valve (1) for a refrigeration system comprises a working element (9) with a diaphragm (15) clamped between a cover plate (12) and a cover ring (10). The diaphragm is a multiple-diaphragm comprising two or more individual diaphragms (16, 17). This makes the multiple-diaphragm more flexible than a single diaphragms and increases the lifetime of the diaphragm. The individual diaphragms are separated by an anti-friction layer to protect against tear, the anti-friction layer can be grease or oil placed between the individual diaphragms or it can be a layer of coating on the diaphragms.

    Abstract: The invention provides a method of making a component (1) from first and second parts (2, 3) which are joined in a welding process wherein a laser beam is transmitted in a direction from a laser source and at least partly into a gap (16). The gap is made between edges (8, 9) of the component (1), and to enable a faster laser welding process, the laser has a focus point (33, 34) size which is at least of the size of the gap. To enable better control of the width of the gap, the invention further provides a method and components (1) wherein one part (2) is formed with a neck (5) which extends into a complementary socket (7) of the other part (3) to prepare the parts for the welding process. The invention in particular concerns welding of brass.
