Complete Technical Solution for Automatic Welding of Corrugated Stainless Steel Hose
1
Overview
Corrugated
stainless steel hose (stainless steel bellows for short) is an important
flexible pipe in modern industrial pipelines. It is widely used in aerospace,
petrochemical industry, mining electronics and mechanical shipbuilding as a
compensation element, sealing element, connecting element and shock-absorbing
element in various gas and fluid pipeline systems and length, temperature,
position and angle compensation systems , Medical and health, textile and
electronics, energy construction and other fields.
The
corrugated stainless steel hose is mainly composed of corrugated pipe, net
sleeve and joint, as shown in Figure 1. The inner tube is a thin-walled stainless
steel corrugated tube with a spiral or circular wave shape. The outer sleeve of
the corrugated tube is woven from stainless steel wire or steel belt according
to certain parameters. The joints at both ends of the hose are either flanges
or wire heads, which have a variety of forms and vary according to the
application conditions.

Complete welding technology for corrugated stainless steel hose
The
welding process of corrugated stainless steel hose generally includes two
processes: (1) welding of mesh sleeve, bellows and compression sleeve—stainless
steel hose body; (2) welding of stainless steel hose body and pipe joint.
2.1
Welding equipment
2.1.1
BW70T corrugated stainless steel hose automatic welding machine
The
stainless steel hose body has a three-layer structure, that is, a mesh sleeve,
a bellows, and a compression sleeve, as shown in Figure 2. The assembly quality
and welding process requirements before welding are strict, and the precision
of the automatic welding machine is high.
The
automatic welding machine for stainless steel hose body has the function of
longitudinal and transverse automatic tracking of the weld seam, real-time
tracking of the roundness of the compression sleeve and the height of the end
face of the mesh sleeve and bellows, which ensures the stability of the welding
process and welding process. Practical application shows that the equipment has
a high degree of automation, accurate positioning of the welding gun, flexible
process adjustment, high repeatability, and stable welding quality.
2.1.1
TPF400T stainless steel hose joint automatic welding machine
The
TPF400T stainless steel hose joint automatic welding special machine, the
welding gun and the displacement mechanism can achieve flexible angle
adjustment, so that the device has wide adaptability, and can complete the
welding of most existing pipe joints such as flanges, elbows, and wire heads.
2.2
Key points of welding process
2.2.1
Main points of welding process of stainless steel hose body
(1)
Due to the special three-layer structure of the stainless steel hose body and
the poor repeatability of the assembly before welding, the welding process must
have sufficient tolerance windows.
(2)
Because the thin-walled parts are very sensitive to the welding line energy,
the welding process requires accurate control of the welding current and
welding voltage, and must be synchronized with the amount of wire filling.
2.2.2
Key points of welding process for stainless steel hose joints
In
general, the thickness of hose joints and compression sleeves are quite
different, and the types of pipe joints are diverse. Therefore, the welding
process should fully consider the influence of the welding angle on the shape
and quality of the weld.

Conclusion
3.1
The bellows stainless steel hose has a wide range of applications and a large
amount of consumption. Its working temperature range can reach -196℃～+420℃, the pressure
range is generally PN0.6-32.0Mpa, the height can reach 42.0MPa, and the weld
quality requirements are high.
3.2
Due to the special multi-layer structure of stainless steel hoses, in order to
ensure the welding quality, higher requirements are placed on the quality of
the counterpart before welding, the welding process, and the welding equipment.
3.3
The BW70T net cover automatic welding machine and the TPF400T joint automatic
welding machine and their supporting welding processes are developed for the
corrugated stainless steel hose welding industry. They have a high degree of
automation, stable process parameter control, strong process adaptability, and
good practical application results.
