Since question is not clear two answers can be given on the assumption that the question is about dry soldering. Thoroughly clean the part to be soldered, apply flux re-solder the connection.
The second answer is normally lead will not be kept on a soldering point. the technician doing soldering has to use lead and flux separately.
================================
There are still solders that contain lead. The European Union prohibited excessive amounts of lead in consumer products (WEEE and RoHS), so there are lead-free solders. But there are industries in which the lead-free solders are not acceptable.
What else can I help you with?
Is lead solder a ferrous metal?
No, lead solder is not a ferrous metal. Ferrous metals contain iron, while lead solder is primarily composed of tin and lead.
Should I use acid or solid or resin core solder for copper pipe?
Use lead-free solder, 0.2 percent lead or less. Lead free means NO Lead your better off with a silver bearing alloy as it has a longer pasty range or 95% tin 5% antimoney Actually the term "solder" means lead bearing according to the AWS specifications
What is the chemical formula for solder?
The chemical formula for solder can vary depending on the type of solder being used, but a common formula is Sn (tin) mixed with Pb (lead), known as Sn-Pb solder. The ratio of tin to lead can differ, with common ratios being 60% tin and 40% lead (60/40 solder) or 63% tin and 37% lead (63/37 solder).
Why is lead-free solder used?
Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.
Solder - lead and tin uses?
A solder is a metal or alloy that has a melting point range of 90 to 450 degrees Celsius (200 to 840 degrees Fahrenheit). The melting point range makes sure that the metal or alloy is easily handled at room temperature, can be melted to join other metallic surfaces when a moderate amount of heat is applied, and returns to a solid state when it cools down to make the joining permanent. Lead has a melting point of 327.46 degrees Celsius (621.43 degrees Fahrenheit) and therefore it can be used as solder. Mercury, however, has a melting point of -38.83 degrees Celsius (-37.89 degrees Fahrenheit) and it is liquid even at room temperature. Therefore it cannot be used as solder because a liquid that does not solidify cannot be expected to join two surfaces permanently.
Is lead solder a ferrous metal?

Solder is made of tin and lead but what is the other chemical?
Traditional electronics solder also contains resin.
What is the chemical formula for solder?
The chemical formula for solder can vary depending on the type of solder being used, but a common formula is Sn (tin) mixed with Pb (lead), known as Sn-Pb solder. The ratio of tin to lead can differ, with common ratios being 60% tin and 40% lead (60/40 solder) or 63% tin and 37% lead (63/37 solder).
What is the compound symbol for solder?
The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).
Do plumbers use solder?
Yes many types depending on application and lead free alloys as solder by definition means lead. Solder such as 40 - 60 50 -50 60- 40
Is solder a lead alloy?
Most commonly, but antimony is another basic component of some solders. The European Union, China, and California are areas where lead solder is banned in consumer products. Tin-lead solders were most often used because they are easily melted and inexpensive. Lead-based solders have a few problems which are reducing their popularity: - Environmental concerns about e-waste - Worker safety concerns for people who constantly work with solder - The low melting point, which is not suitable for modern microprocessors Any metal which is melted to bond to another metal is a solder. Silver solder is used to repair silver jewelry, and gold solder to repair gold. Silver solder is also used in food-grade plumbing. Drinking water is soldered with lead-free solder (but lead was used in nearly all plumbing soldering until the late 1980s).
Lead pipe connected to copper pipe?
Easiest way to connect lead to copper /brass is a wiped joint consisting 40 - 60 solder alloy as this gives a longer pasty range
Is solder a element or a compound?
It is a mixture
What products are made using soft solder?
soft solder is made of tin and lead. :D
Which alloy is made from tin and lead?
Solder
What type of solder is used in electronics and why?
lead.
