In addition to standard welding, the welder must choose a quality silver solder wire and use a reasonable welding machine to bring about a good work result. This article will outline a few welding notes so that users can make good use of a durable and beautiful weld.
Selection of solder wire
Solder wire is a soft, fusible metal that is an alloy consisting of tin and lead.
For lead-free solder wire
Lead tin is a ratio of 63/37 to produce shiny and easy-to-melt welds, which are often soldered to a special-use Eutectic alloy. With a tin-lead ratio of 60/45xUdHPiFHQ7xbKh19G45saF1raB2ot5pag8p1Hnk4yrfXRJZskr8TMbFpVfC5tDk8eQQg63TqkW9gKhwagx6HePTaK2yXb wire: Includes 96 tin, 3 silver and 1 copper according to the ratio of alloy formation, high cost and good soldering quality.
Solder flux in solder wire core
Solder wire has many types and each type has one or more cores with flux, so when we solder we do not need to add flux. The effect of flux is to use a part of the acid contained in it to clean the weld to make the solder joints shinier. Usually this flux is usually rosin or cleaning solvent. Outside is silver solder grease, which is also a substance to clean the solder joint to help the solder
adhere to the solder joint.
You can completely manually add this flux by smashing the turpentine with an Esaki plastic ball hammer and mixing it with gasoline, stirring until you see that the turpentine has dissolved into the gasoline, the phenomenon that occurs in the state of the solution turned dark yellow. This manual method you only apply with a small amount, when you do it, you can create it, if you have excess.
How to choose solder wire?
The experience for customers when buying solder wire is to bring a gas lighter to buy, if you choose, you can melt a small piece on the solder wire to make them fall down to form smooth balls. Round, let it cool when you pick it up so it won't blacken your hand. As for silver solder that is black when held, it contains too much lead.
Reasonable welding temperature
Using a soldering temperature that is too high will burn the circuit, and if the temperature is too low, the solder will not be able to melt and crumble. Normally, the melting temperature of solder wire is from 200 - 280 degrees Celsius, so the temperature fluctuation when soldering can be from 240 - 320 degrees is reasonable for good solder joints.
Paste components, IC, the reasonable temperature is 240 - 260 degrees Celsius. Removable components, connectors, the suitable melting temperature is 280 degrees. Depending on the value of the welding component, the appropriate welding temperature should be selected to ensure that the silver solder circuits are not damaged, creating obstacles for the welder.
Steps to create a beautiful and solid weld
Fix the solder, solder board
Adjust the appropriate welding temperature level
When you see smoke, it means that the welding machine has enough heat, keeping the heat stable without further heating.
Put the solder wire and the metal pin next to the solder tip so that the tin can melt
Beautiful welds are not superfluous, not lumpy, not lacking
Which solder is suitable for welder?
In addition to standard welding, the welder must choose a quality silver solder and use a reasonable welding machine to bring about a good work result. This article will outline a few welding notes so that users can make good use of a durable and beautiful weld.

For lead-free solder wire
Lead tin is at a ratio of 63/37 to produce shiny and easy-to-melt welds, which are often soldered to a special-use Eutectic alloy. With a tin-lead ratio of 60/40, the melting point is high and the silver solder is looser and less glossy.
Lead-free solder wire
It Consists of 96 tin, 3 silver and 1 copper according to the ratio of alloy formation, high cost and good welding quality.

In the industry, the profession of welder is in great demand and has been expanding; a consequence of this is the evolution in the matter of materials and techniques.
Safety measures in silver soldering
Even with new technologies, these professionals are constantly exposed to risks in their work. Be it with heat, projection of materials, inhalation of smoke, noise or others.
In view of this, the use of Personal Protective Equipment (PPE) for silver solder is essential and deserves attention.
During the soldering process
Essential PPE for silver solder, as the professional is subject to several accidents during the welding process, ranging from mild burns to blindness. As such, it is vital to seek protection. One such means of protection is the Welding Mask.
The purpose of PPE is to eliminate or reduce as much as possible any form of injury that may happen to the professional.
