When it comes to lead free welding wire, we immediately think of this as a high-quality product. It is often common in daily life. To better understand Best Lead-Free Soldering process in the article below. We will go into understanding its characteristics as well as its applications.
What is lead free welding wire?
Lead free welding wire is a type of wire with high quality, high nickel content, less impurities. When welding, there is no splashing. The wire stacks in layers and is easy to weld with any MIG welder.
Features of lead-free welding wire
- Shiny mirror
- Thickness is 0.8mm
- Usually has a weight of 15kg / 1 roll.
- Imported goods with high nickel content, low impurities should always ensure smooth, beautiful welds, less welding and easy manipulation by workers.
Best Lead-Free Soldering process has low carbon content, medium manganese content, very small sulfur and phosphorus impurities. This creats welds with high strength and ductility. Especially with nickel and chromium content to ensure that welds are stainless, not corrode acids.
Lead free welding wire comes with high precision
Moreover, lead free welding wire is suitable for welding steel of all kinds such as: with good quality, high strength and toughness.
Lead free welding wire sells by semi-automatic technology with 100% shielding gas. This type welds well, with little spatter and bright welds.
Applications of lead-free welding wire
- The product apply in structures subject to heavy loads and high wear resistance.
- Suitable for welding chemical, acid-resistant, bearing-bearing tanks as well as other medical equipment.
How to use Best Lead-Free Soldering process?
- Before welding, we must prepare protective elements to ensure labor safety before welding.
- Make sure the power supply is stable.
- Clean off dirt such as oil, rust, stuck on the surface of the object to solder, then proceed with the welding steps in accordance with the regulations, in the sequence.
- Clean the solder tip, conduit, adjust the wire guide mechanisms reasonably so that the solder wire charges stably, do not let the welding wire bending.
- In case the welding wire is wet, dusty, smoke splashes, unstable, it is advisable to stop to check the welding wire.
- Should store Best Lead-Free Soldering processin a dry place, avoid contact with dust, moisture, avoid contact with welding wire surface.
- When welding should choose a welding current, should shield the wind to get an error-free and beautiful weld for high efficiency during use.
304 lead free wire is the standard grade
It is the most versatile and most widely common lead free available in a wide range. This type is widely common in the fields of architecture and in transportation works. In industry, it really makes excellent welds especially in thin welds.
Best Lead-Free Soldering process has many uses in the applications of life
It is very necessary for sophisticated welds, using lead free welding wire will bring accurate and beautiful welds. This is very necessary for items such as medical devices and objects subject to heavy loads and high wear resistance.
For each welding wire technology, different forming steps are indispensable and they go through at least one drawing operation.
CO2 or submerged arc welding wires form from wires of drawn material: They draw with drawing soap, after pickle (elimination of the oxides of the wire rod) in a mechanical or chemical way. Then they are usually copper plated, either directly or after submerged drawing, before packing.
Welding electrodes produce from drawn wire
Aluminum, they are usually drawn with oil. Welding electrodes produce from drawn wire, straightened and cut and then coated with solder flux.
Best Lead-Free Soldering process produce from laminated sheet metal, filled with solder flux and then drawn with solid lubricants, and in certain cases with liquid lubricants.
Characteristics of lead-free soldering process
The CO2 wire or steel submerged arc welding market is highly competitive. The lubrication processes implemented must provide an increasingly higher level of productivity (drawing speed, surface quality). A quality weld wire characterizes by its slip and conductivity properties, achieved through the use of drawing lubricants, often in the last pass.
Welding electrodes are drawn very economically. The Best Lead-Free Soldering process surface must clean prior to the straightening, cutting and solder flux coating step.
Like submerged arc welding CO2 wires, wires with solder flux in the core must have excellent surface properties: slip, conductivity and no contaminant to the weld. These wires can undergo a recrystallization heat treatment, “baking”.
Applications of lead-free soldering process
CO2 or submerged arc welding wires may combine a first dry drawing operation, followed by a submerged drawing operation.
In this case, it is important to verify the combination of these two technologies in order to ensure a great durability of the soluble lubricant, cleaning the wire before copper plating. In fact, drawing soaps carried in the lubricant by the wire are not necessarily compatible.
Best Lead-Free Soldering process is so called because the filler material, which by melting transfer to the weld pool, is in the form of skeins of continuous wire.
The welding needs that can be more or less complicated
They are the type of welding machine to be common and the type of metals to weld that allow you to determine. This is the best welding wire, in addition to the welding needs that can be more or less complicated.
Choosing the best welding wire, be it bare wire or lined wire. This requires some professional skill and knowledge of materials. Therefore, before making the purchase it is always important to hear the opinion of an expert.
How to choose the Best Lead-Free Soldering process for welding?
The choice of the best welding wire must come with due attention and the evaluation must base on the quality of the material that composes it.
The basic elements that characterize the welding wire are the structure of the stem. The chemical composition, indicated in the marking of the wire, and the presence of the binder component.
Classification of wires into groups and subgroups
In addition to these fundamental elements, we can say that the wires generally classify into three groups: low carbon content, with small quantities of alloying elements and wires with a high content of alloying elements.
Each of these three groups divides into further subgroups, depending on the structure of the wire. Various welding processes involve the use of copper-core coated steel wire. As in the case of welding low carbon metals and alloy steel.
The choice of wire and Best Lead-Free Soldering process depends on the quality of the materials. The guidelines for the choice mainly indicate in the marking of the welding wire.
