Overview of welding process for hardware partsOur company has
strong welding core competitiveness, and uses fully automatic
equipment to flexibly accept parts welding processes from all walks
of life. Various parts and components can be welded through copper
loading, copper fetching, solder paste dripping, silver spot
fetching, silver spot detection and positioning, silver spot
welding, finished product fetching, and finished product fetching
detection Advantages and highlights of welding process
equipment for hardware parts1. The key process (mass
production contact) adopts fully automatic production. Dynamic and
static dual vision backup detection can effectively solve the
problem of reverse spot and high penetration rate level in the
industry by 90%.2. Workshop welding equipment adopts medium
frequency power supply, servo motor pressurization, automatic
pressure detection display and automatic defect alarm, ensuring
zero defect requirements for products3. The welding process
shall be standardized. Standardized electrode processing,
standardized electrode use, standardized electrode maintenance and
standardized data management completely solve the problem of
unstable welding process4. It has a number of key process
technologies. Such as indirect heating resistance brazing process,
induction brazing process and automatic
welding after grinding (for welding problems of different
materials).5. The infrared temperature control technology is
used to precisely control the welding parameters, which ensures the
welding quality and greatly improves the service life of the
product by 50%.6. Side heating resistance welding process: the
silver spot welding transfers heat from copper heating to silver
spot welding. The silver spot has no electrical corrosion damage,
which does not cause the silver spot surface to fade and become
soft. It retains the original state of the silver spot. The contact
has no damage, and the welding consistency is good, which increases
the mechanical life and electrical life of the contact point by
15%.7. In order to ensure the product quality, we check the
leakage and make up for defects, and ensure the product quality,
after the completion of welding, ultrasonic nondestructive testing,
metallographic testing of welds, tensile testing, shear force
testing and other means are used to comprehensively cover the
elements of weld joint identification, and the quality risk of each
period is strictly controlled through the first inspection, process
inspection, completion inspection, factory inspection and other
control means to ensure that the product leaves the factory with
zero defects. Welding process flow of hardware partsCopper
material-----punching and forming-----pickling-----surface
treatment/electroplating of copper
parts-----welding Our after-sales rate of copper electroplating does not exceed 3 in 7 years.1. After
degreasing agent, pickling, cleaning, silver plating (the printing
plate is converted into silver molecules by electrolysis, and then
adsorbed on the copper by electrodes), cleaning, drying, drying at
100 ºC and other processes, the following parts are
obtained.2. Our copper electroplating silver content is up to
99.9999999%.3. Through 7.5% potassium sulfide experiment, the
time can be as long as 15 minutes, it solves the defects of
unstable welding and discoloration of copper parts in the same
welding process. The function is to ensure that the electroplated
coating does not blacken and discolor within the specified
time.FAQ1.Q: Are you trading company
