Lead-free environmentally friendly tin bars play a very important role in welding work. Tin bars made of different alloy compositions also have different properties and uses. When using lead-free environmentally friendly tin bars, you need to pay attention to the following aspects:
(1) Pay attention to the height of the liquid level in the soldering furnace, and the tin inside should not be too much or too little, and the technicians should pay attention to reasonable control;
(2) The melting point of lead-free environmentally friendly tin bars is very important. Pay attention to several commonly used melting points. The melting point of tin bars is related to the operating temperature, which is determined by the alloy composition itself;
(3) To use an environmentally friendly lead-free solder furnace, when using lead-free environmentally friendly tin bars, whether it is a solder furnace or a solder flux, lead-free must be selected, so as to meet the environmental protection requirements, rather than Use with lead stoves;
(4) There are many types of lead-free environmentally friendly tin bars. It is necessary to find out which alloy composition of lead-free environmentally friendly tin bars you choose, such as: tin-copper alloy Sn99.3Cu0.7 or silver-containing 0.3 lead-free tin bar Sn99 .0Ag0.3Cu0.7 or high temperature lead-free tin bars, etc., the performance and use of different alloys will be different;
(5) Lead-free environmentally friendly tin bars are usually used together with flux. Therefore, attention should be paid to the purchase of lead-free flux. Lead-free flux should be able to withstand high temperature conditions, with better activity, and no-clean type without Lead flux, which can improve the welding efficiency to a certain extent in the lead-free environmental protection tin bar welding work.
