There is provided an inexpensive bonding material, which can be easily printed on articles to be bonded to each other and which can suppress the generation of voids in the bonded portions of the articles to be bonded to each other, and a bonding method using the same. In a bonding material of a copper paste which contains a copper powder containing 0.3 % by weight or less of carbon and having an average particle diameter of 0.1 to 1 µ m, and an alcohol solvent, such as a monoalcohol, a diol, a triol or a terpene alcohol, the content of the copper powder is in the range of from 80 % by weight to 95 % by weight, and the content of the alcohol solvent is in the range of from 5 % by weight to 20 % by weight.
摘要:
An automated oxy-fuel thermal processing system including an oxy-fuel torch, an automated machine tool operatively coupled to the torch for moving the torch relative to a work piece, and a circuit including a voltage source or a current electrically connected to the torch and configured to be electrically connected to the work piece. The automated oxy-fuel thermal processing system may further include a processor that is operatively connected to the torch, the automated machine tool, the circuit, and the voltage source or current source, wherein the processor is configured to control the operation of the torch, the automated machine tool and the voltage source or current source, and to monitor a current or voltage in the circuit in a predefined manner.

摘要:
In a flame cutting machine, a removable tool element of a tool mounted in a carriage station of at least one burner carriage can be fixed automatically. The burner carriage can travel on a machine housing which can itself travel in a direction at right angles to that of the carriage. To facilitate rapid exchange of tool elements without detriment to the operational range of the burner carriage, a tool element receiving element (7) with cover (8) is provided with a number of tool element receiving stations in such a way as to be suitable for mounting a group of interchangeable tool elements (14-19) and allow said tool elements to slide vertically and to be inserted and removed. The tool element receiving unit (7) can be controllably adjusted with an adjusting device (22) from a position closed with the cover (8) into an open tool element removal position. This means that a selected tool element receiving station is in a predetermined position in relation to a tool element insertion- and removal device and to the burner carriage (4).
