The whole world
is made up with numerous big things constructed by engineers. It consists of
huge buildings, machinery, automotives, electronics and so on. Every process is
elaborate and is made up of a lot of activities. Joining of two metals is a
very common activity here and this is known as soldering. It is very common to
see joining of same or different metals while manufacturing and building
activities. Soldering has been used interchangeably with welding but this is
completely incorrect. The two processes are different as welding involves
melting of pieces while soldering does not.
In the past,
solder sticks and solder bars were made up of lead but with increasing pressure
of environmental concerns, these are now being replaced with lead-free alloys
for use in electronics and plumbing activities. There are many soldering
products that you may have heard of but may not know their exact usage and
features. Some of the common types of products are given below:
·
Solder sticks are most commonly
used for electronics and these easily dissolve the metals gold and silver.
These are also highly resistant to water and moisture
·
Solder wires also come with
different levels of thickness as per the requirements of hand soldering. These
are used as lead free which is a bit difficult for hand soldering than lead
wires but these are environmentally friendly
·
Solder bars are thicker than
wires and are preferred for use by the plumbers
Besides the
above mentioned products, solder flux is also very famous. In the electronics
industry, rosin flux were used that were found to be hazardous and now water
soluble flux is used that can be removed by detergent very easily. These
solders are extensively used and it is used for joining two or more glasses.
The glass and ceramics are also joined with glass solders. The filler materials
are found in different alloys for applications in different industries. With
changing time and needs, the materials will keep changing and you will see many
new and advanced techniques in the coming times.
